Changes in version 1.1-2 (2021-06-07)
o Miwa(n) now also works for non-zero mean|delta; n <= 4097, not 4098 (from C code);
optional 'checkCorr=' argument; documentation, one NOTE less.
Minimal C code cleanup.
mvt() <-> probval() simplification.
Handles +/-Inf as +/-maxval for non-orthrant probabilities (with a warning).
o TVPACK() now also works when some (but not all) bounds are (-Inf, Inf).
o mvtnorm() and mvt() now also return an attribute "algorithm" and gain optional
argument 'keepAttr' to allow returning bare numbers.
Changes in version 1.1-1 (2020-06-09)
o allow to turn-off symmetry checks (patch contributed by Feng Li <feng.li_at_cufe.edu.cn>
Changes in version 1.1-0 (2020-02-24)
o replace MVPHI and MVPHNV by calls to R's {p,q}norm5, following
a suggestion by Benjamin Christoffersen <boennecd_at_gmail.com>
Changes in version 1.0-12 (2020-01-06)
o fix Rdiff issues
Changes in version 1.0-11 (2019-06-19)
o improve documentation and error messages
Changes in version 1.0-10 (2019-03-04)
o eliminate warning when calling qmvt with arg sigma = 1
Changes in version 1.0-9 (2019-02-28)
o adapt to recent changes in r-devel
Changes in version 1.0-8 (2018-05-31)
o pmvt(..., sigma = ) was ignored in the univariate case
(reported by Alec Stephenson)
o documentation updates
Changes in version 1.0-7 (2018-01-25)
o pmvt(..., df = ) is scalar only
Changes in version 1.0-6 (2017-03-01)
o use registered C routines
Changes in version 1.0-5 (2016-02-02)
o improvements in quantile estimation
Changes in version 1.0-4 (2016-01-19)
o a new algorithm for quantile estimation, again. Quantiles are
now computed by a stochastic root finding algorithm. Note
that f.quantile in the output of qmv{t,norm} is now (again)
the squared difference between the cdf evaluated at the
quantile and the level. The \code{interval} argument to the
quantile functions is used as a starting value for the
root finder when available.
o clean-ups in C and R code and documentation
Changes in version 1.0-3 (2015-07-21)
o new algorithm for quantile estimation. Quantiles are
now computed by minimising the squared distance between the
distribution function and the probability whereas previous versions
used uniroot(). The procedure is now performed multiple times with
difference random seeds in order to stabilise the results. The
\code{interval} argument to the quantile functions is IGNORED now.
Changes in version 1.0-2 (2014-12-16)
o start providing C interfaces to the underlying algorithms.
mvtnorm_C_mvtdst() directly calls Alan's FORTRAN code and
can be used in other packages via LinkingTo. See
mvtnorm/inst/C_API_Example for an example very much inspired
by the example provided in package xts.
o provide .C interfaces to the FORTRAN routines and allow switching
on/off of R' RNG.
Changes in version 1.0-1 (2014-11-11)
o replace internal MVCHNV FORTRAN FUNCTION with
R's sqrt(qchisq(p, n, FALSE, FALSE). This fixes a
problem where NaN was returned as reported by
David Charles Airey <airey_david_charles_at_lilly.com>
Changes in version 1.0-0 (2014-07-08)
o After 14 years, we now feel safe enough to publish mvtnorm 1.0-0.
Many packages depend, import, or suggest mvtnorm, so this version
change also indicates that the package is now stable and, to a very
large extent, the API is frozen. We will of course continue to fix
bugs or other problems but new features are unlikely to go into this
package.
o use Authors@R in DESCRIPTION

rmvnorm(100, ...)
o as suggested by Paul Johnson <pauljohn_at_ku.edu>. There is a new
argument pre0.9_9993 for changing back to the `old' output. This
_DOES NOT_ apply to rmvt.
Changes in version 0.9-9993 (2012-10-22)

for unknown reasons. Redefining TVTL and BVTL as FUNCTIONs
fixed the problem.
Changes in version 0.9-999 (2011-04-26)

Highest Density Regions are the smallest set in the support of a
probability distribution with the specified coverage probability.
'HDRs' may contain disjoint intervals, but can be calculated
efficiently using iterative methods. One can similarly construct
optimal (i.e., shortest) confidence intervals for some basic
inferential problems, including for population means, variances, or
proportion parameters.

Version 2.0-1.9001
Minor changes / Bugfixes:
* functions that do not work with sticky classes are now wrapped
(e.g. `anova()`)
Version 2.0-1.9000
Major change: sticky classes!
Now objects of compositional classes do not miss their class
when subsetting. For example, if `x` is an "acomp" object,
x[1:2,] will also be an "acomp" object. Selection of columns work
as well, but it is a bit more tricky. Check ?`[.acomp` for
details. You can get skip this behaviour by setting
setStickyClassOption(FALSE). The dollar notation `$` also works!
Added:
* Limited support for using compositions classes as formal S4
classes, for instance in slots of S4 classes expecting a
"data.frame" or a "structure" (matrix or array).
* self-invertibility: now "rmult" objects created by any
transformation (cdt, clr, cpt, idt, ilr, ipt, iit, ilt, alr,
apt) remember the original data and the transformation between
them, and can be back-transformed with `backtransform`.
* added cdt and idt methods for objects of class "factor" (returning
the contrasts and their ipt transformation), and for "data.frame"
objects (exploiting the attribute "origClass" if they have it).
* `pwlr()`: pairwise logratio transformation (and inverse: `pwlrInv()`)
* `pwlrPlot()`: pairwise logratio plots vs covariables, both as explained
and as explanatory variables. This makes use of the ability of plot(x~y)
to react to the nature of `x` and `y` to create scatterplots, boxplots
and spineplots.
* transformation functions between variation and clrvar: variation2clrvar
and clrvar2variation
* `split()` methods for compositional classes
* new panels for filling `pairs()` plots with boxplots, densities,
kde2d-densities, etc...: check ?vp.kde2dplot
Minor Changes:
* the function to fit linear models of coregionalisation is now called
`fit.lmc()`; use full name specification with it! `compositions::fit.lmc()`
Bugfixes:
* bug in subsetting of one-column rmult object corected
## Version 3.1.2 (July 31, 2021)
Patch release that fixes a Windows header issue.
* Improve handling of ``#include <*intrin.h>``
## Version 3.1.1 (July 20, 2021)
Patch release that fixes a build failure on ARM64 macOS
## Version 3.1.0 (July 13, 2021)
Minor release with new features:
* Optimized half-to-float and float-to-half conversion, using F16C SSE
instruction set if available. Non-SSE conversion eliminates the
float-to-half exponent lookup table, and half-to-float conversion
provides a compile-time-optional bit shifting that is slower but
eliminates the need for the lookup table, for applications where
memory is limited.
Half-to-float and float-to-half conversion is also available as
C-language functions ``imath_half_to_float()`` and
``imath_float_to_half()``.
All new conversions produced identical results, and new options are
off by default to ensure backwards compatibility. See
https://imath.readthedocs.io for more info.
* NOEXCEPT specifier can be eliminated at compile-time via the
``IMATH_USE_NOEXCEPT`` CMake option.
* Python bindings:
* FixedArray objects support a "read only" state.
* FixedArray objects support python buffer protocol.
* Optimized 4x4 matrix multiplication.
Upstream changes:
CHANGES IN R 4.1.1:
NEW FEATURES:
* require(pkg, quietly = TRUE) is quieter and in particular does
not warn if the package is not found.
DEPRECATED AND DEFUNCT:
* Use of ftp:// URIs should be regarded as deprecated, with
on-going support confined to method = "libcurl" and not routinely
tested. (Nowadays no major browser supports them.)
* The non-default method = "internal" is deprecated for http:// and
ftp:// URIs for both download.file and url.
* On Windows, method = "wininet" is deprecated for http://,
https:// and ftp:// URIs for both download.file and url. (A
warning is only given for ftp://.)
For ftp:// URIs the default method is now "libcurl" if available
(which it is on CRAN builds).
method = "wininet" remains the default for http:// and https://
URIs but if libcurl is available, using method = "libcurl" is
preferred.
INSTALLATION:
* make check now works also without a LaTeX installation. (Thanks
to Sebastian Meyer's PR#18103.)
BUG FIXES:
* make check-devel works again in an R build configured with
--without-recommended-packages.
* qnbinom(p, size, mu) for large size/mu is correct now in a range
of cases (PR#18095); similarly for the (size, prob)
parametrization of the negative binomial. Also qpois() and
qbinom() are better and or faster for extreme cases. The
underlying C code has been modularized and is common to all four
cases of discrete distributions.
* gap.axis is now part of the axis() arguments which are passed
from bxp(), and hence boxplot(). (Thanks to Martin Smith's
report and suggestions in PR#18109.)
* .First and .Last can again be set from the site profile.
* seq.int(from, to, *) and seq.default(..) now work better in large
range cases where from-to is infinite where the two boundaries
are finite.
* all.equal(x,y) now returns TRUE correctly also when several
entries of abs(x) and abs(y) are close to .Machine$double.xmax,
the largest finite numeric.
* model.frame() now clears the object bit when removing the class
attribute of a value via na.action (PR#18100).
* charClass() now works with multi-character strings on Windows
(PR#18104, fixed by Bill Dunlap).
* encodeString() on Solaris now works again in Latin-1 encoding on
characters represented differently in UTF-8. Support for
surrogate pairs on Solaris has been improved.
* file.show() on Windows now works with non-ASCII path names
representable in the current native encoding (PR#18132).
* Embedded R on Windows can now find R home directory via the
registry even when installed only for the current user
(PR#18135).
* pretty(x) with finite x now returns finite values also in the
case where the extreme x values are close in size to the maximal
representable number .Machine$double.xmax.
Also, it's been tweaked for very small ranges and when a boundary
is close (or equal) to zero; e.g., pretty(c(0,1e-317)) no longer
has negative numbers, currently still warning about a very small
range, and pretty(2^-(1024 - 2^-1/(c(24,10)))) is more accurate.
* The error message for not finding vignette files when weaving has
correct file sizes now. (Thanks to Sebastian Meyer's PR#18154.)
* dnbinom(20, <large>, 1) now correctly gives 0, and similar cases
are more accurate with underflow precaution. (Reported by
Francisco Vera Alcivar in PR#18072.)
0.8.2
Changes
- Improved yank and undo alloc'ing. Malloc as much we need from start
in a long batch and avoid small mallocs.
- Changed the way lua scripts are referenced in formulas. Now they are
input as any other string formula, like this:
\"@lua("script_name.lua", 1) being 1 if the reference should be added
to the depgraph or not, making it evaluated just once or every time
the depgraph is evaluated.
NOTE that if set to 0 and the cell is referenced by another cell, it
will be executed nonetheless.
- Added new exec_lua configuration variable.
- Rows now can have height higher than one LINE. See fj and fk in
normal mode or :formatrow in command mode.

This delivers 64 bit index BLAS libraries alongside 32 bit ones. This is often
called ILP64 in the BLAS world, as opposed to LP64 where integers are 32 bit
due to the Fortran default integer type, not to be confused with the basic
system ABI used by C. For really large vectors on modern machines, you want
an 'ILP64' BLAS and layers on top of it.
In preparation of better support for vendor BLAS libraries, I had to realize
that you better use the C interfaces supplied by them, not the netlib one
strapped on. A simple reason of practicability: The vendor blas libraries,
just like openblas, like to ship all symbols in one library, so you get them
whether you want it or not. Also implementations may skip Fortran and implement
the underlying functionality directly in C anyway, so one might skip a
layer of indirection. Future will tell if other layers will follow. We still
have the framework of individual layers from Netlib to combine with certain
implementations that miss them (Accelerate framework comes to mind, which
needs further work).
The framework of netlib reference packages for the separate libraries
is instructive and helps keeping things small when you not need all of them.
The installation location of the headers is now in a subdirectory to be able
to have 32 and 64 bit variants independently. The 32 bit ones are linked to
${PREFIX}/include to keep the old picture. We could be brave and remove
those, but there is some value in a build just trying -lcblas and
inclusion of <cblas.h> to be happy.
There is one blas.buildlink3.mk that is supposed to be used only once and
so avoids a combination of conflicting libraries (as the 64 bit index symbols
have the same names as the 32 bit ones).
Basic usage for getting LAPACK+BLAS is still the same as before. You get
CBLAS and LAPACKE by setting BLAS_C_INTERFACE=yes in the package. The 64 bit
indices are selected via BLAS_INDEX64=yes.
Due to the special nature of the Accelerate framework, a package has to
explicitly indicate support for it and it will also not appear on the
list of implementations by default. The reason is that it does provide
mainly CBLAS and CLAPACK (another version of C interface to LAPACK, f2c-based)
and BLAS/LAPACK with f2c/g77 calling conventions. A default build with
gfortran would not like that
This commit also fixes up math/py-numpy and math/py-numpy16 to follow the
new scheme, as that are the only packages directly affected by the change
in CBLAS providership.
Change the way iconv_t void* conflict is handled
using a patch from upstream to fix PR pkg/56240 .
Due to the above remove
patch-libinterp_corefcn_input.cc and
patch-liboctave_wrappers_iconv-wrappers.h .
Execute autoconf in the configuration step so that
patch-configure.ac and patch-m4_acinclude.m4 is
actually used.
Change the PLIST so that -gnu is not used
references in patch-m4_acinclude.m4 mentions this.

CHANGES IN R 4.1.0:
FUTURE DIRECTIONS:
* It is planned that the 4.1.x series will be the last to support
32-bit Windows, with production of binary packages for that
series continuing until early 2023.
SIGNIFICANT USER-VISIBLE CHANGES:
* Data set esoph in package datasets now provides the correct
numbers of controls; previously it had the numbers of cases added
to these. (Reported by Alexander Fowler in PR#17964.)
NEW FEATURES:
* www.omegahat.net is no longer one of the repositories known by
default to setRepositories(). (Nowadays it only provides source
packages and is often unavailable.)
* Function package_dependencies() (in package tools) can now use
different dependency types for direct and recursive dependencies.
* The checking of the size of tarball in R CMD check --as-cran
<pkg> may be tweaked via the new environment variable
_R_CHECK_CRAN_INCOMING_TARBALL_THRESHOLD_, as suggested in
PR#17777 by Jan Gorecki.
* Using c() to combine a factor with other factors now gives a
factor, an ordered factor when combining ordered factors with
identical levels.
* apply() gains a simplify argument to allow disabling of
simplification of results.
* The format() method for class "ftable" gets a new option justify.
(Suggested by Thomas Soeiro.)
* New ...names() utility. (Proposed by Neal Fultz in PR#17705.)
* type.convert() now warns when its as.is argument is not
specified, as the help file always said it _should_. In that
case, the default is changed to TRUE in line with its change in
read.table() (related to stringsAsFactor) in R 4.0.0.
* When printing list arrays, classed objects are now shown _via_
their format() value if this is a short enough character string,
or by giving the first elements of their class vector and their
length.
* capabilities() gets new entry "Rprof" which is TRUE when R has
been configured with the equivalent of --enable-R-profiling (as
it is by default). (Related to Michael Orlitzky's report
PR#17836.)
* str(xS4) now also shows extraneous attributes of an S4 object
xS4.
* Rudimentary support for vi-style tags in rtags() and R CMD rtags
has been added. (Based on a patch from Neal Fultz in PR#17214.)
* checkRdContents() is now exported from tools; it and also
checkDocFiles() have a new option chkInternal allowing to check
Rd files marked with keyword "internal" as well. The latter can
be activated for R CMD check via environment variable
_R_CHECK_RD_INTERNAL_TOO_.
* New functions numToBits() and numToInts() extend the raw
conversion utilities to (double precision) numeric.
* Functions URLencode() and URLdecode() in package utils now work
on vectors of URIs. (Based on patch from Bob Rudis submitted
with PR#17873.)
* path.expand() can expand ~user on most Unix-alikes even when
readline is not in use. It tries harder to expand ~, for example
should environment variable HOME be unset.
* For HTML help (both dynamic and static), Rd file links to help
pages in external packages are now treated as references to
topics rather than file names, and fall back to a file link only
if the topic is not found in the target package. The earlier rule
which prioritized file names over topics can be restored by
setting the environment variable _R_HELP_LINKS_TO_TOPICS_ to a
false value.
* c() now removes NULL arguments before dispatching to methods,
thus simplifying the implementation of c() methods, _but_ for
back compatibility keeps NULL when it is the first argument.
(From a report and patch proposal by Lionel Henry in PR#17900.)
* Vectorize()'s result function's environment no longer keeps
unneeded objects.
* Function ...elt() now propagates visibility consistently with
..n. (Thanks to Lionel Henry's PR#17905.)
* capture.output() no longer uses non-standard evaluation to
evaluate its arguments. This makes evaluation of functions like
parent.frame() more consistent. (Thanks to Lionel Henry's
PR#17907.)
* packBits(bits, type="double") now works as inverse of
numToBits(). (Thanks to Bill Dunlap's proposal in PR#17914.)
* curlGetHeaders() has two new arguments, timeout to specify the
timeout for that call (overriding getOption("timeout")) and TLS
to specify the minimum TLS protocol version to be used for
https:// URIs (_inter alia_ providing a means to check for sites
using deprecated TLS versions 1.0 and 1.1).
* For nls(), an optional constant scaleOffset may be added to the
denominator of the relative offset convergence test for cases
where the fit of a model is expected to be exact, thanks to a
proposal by John Nash. nls(*, trace=TRUE) now also shows the
convergence criterion.
* Numeric differentiation _via_ numericDeriv() gets new optional
arguments eps and central, the latter for taking central divided
differences. The latter can be activated for nls() via
nls.control(nDcentral = TRUE).
* nls() now passes the trace and control arguments to getInitial(),
notably for all self-starting models, so these can also be fit in
zero-noise situations via a scaleOffset. For this reason, the
initial function of a selfStart model must now have ... in its
argument list.
* bquote(splice = TRUE) can now splice expression vectors with
attributes: this makes it possible to splice the result of
parse(keep.source = TRUE). (Report and patch provided by Lionel
Henry in PR#17869.)
* textConnection() gets an optional name argument.
* get(), exists(), and get0() now signal an error if the first
argument has length greater than 1. Previously additional
elements were silently ignored. (Suggested by Antoine Fabri on
R-devel.)
* R now provides a shorthand notation for creating functions, e.g.
\(x) x + 1 is parsed as function(x) x + 1.
* R now provides a simple native forward pipe syntax |>. The
simple form of the forward pipe inserts the left-hand side as the
first argument in the right-hand side call. The pipe
implementation as a syntax transformation was motivated by
suggestions from Jim Hester and Lionel Henry.
* all.equal(f, g) for functions now by default also compares their
environment(.)s, notably via new all.equal method for class
function. Comparison of nls() fits, e.g., may now need
all.equal(m1, m2, check.environment = FALSE).
* .libPaths() gets a new option include.site, allowing to _not_
include the site library. (Thanks to Dario Strbenac's suggestion
and Gabe Becker's PR#18016.)
* Lithuanian translations are now available. (Thanks to Rimantas
Zakauskas.)
* names() now works for DOTSXP objects. On the other hand, in
R-lang, the R language manual, we now warn against relying on the
structure or even existence of such dot-dot-dot objects.
* all.equal() no longer gives an error on DOTSXP objects.
* capabilities("cairo") now applies only to the file-based devices
as it is now possible (if very unusual) to build R with Cairo
support for those but not for X11().
* There is optional support for tracing the progress of
loadNamespace() - see its help.
* (Not Windows.) l10n_info() reports an additional element, the
name of the encoding as reported by the OS (which may differ from
the encoding part (if any) of the result from
Sys.getlocale("LC_CTYPE").
* New function gregexec() which generalizes regexec() to find _all_
disjoint matches and well as all substrings corresponding to
parenthesized subexpressions of the given regular expression.
(Contributed by Brodie Gaslam.)
* New function charClass() in package utils to query the
wide-character classification functions in use (such as
iswprint).
* The names of quantile()'s result no longer depend on the global
getOption("digits"), but quantile() gets a new optional argument
digits = 7 instead.
* grep(), sub(), regexp and variants work considerably faster for
long factors with few levels. (Thanks to Michael Chirico's
PR#18063.)
* Provide grouping of x11() graphics windows within a window
manager such as Gnome or Unity; thanks to a patch by Ivan Krylov
posted to R-devel.
* The split() method for class data.frame now allows the f argument
to be specified as a formula.
* sprintf now warns on arguments unused by the format string.
* New palettes "Rocket" and "Mako" for hcl.colors() (approximating
palettes of the same name from the 'viridisLite' package).
Contributed by Achim Zeileis.
* The base environment and its namespace are now locked (so one can
no longer add bindings to these or remove from these).
* Rterm handling of multi-byte characters has been improved,
allowing use of such characters when supported by the current
locale.
* Rterm now accepts ALT+ +xxxxxxxx sequences to enter Unicode
characters as hex digits.
* Environment variable LC_ALL on Windows now takes precedence over
LC_CTYPE and variables for other supported categories, matching
the POSIX behaviour.
* duplicated() and anyDuplicated() are now optimized for integer
and real vectors that are known to be sorted via the ALTREP
framework. Contributed by Gabriel Becker via PR#17993.
GRAPHICS:
* The graphics engine version, R_GE_version, has been bumped to 14
and so packages that provide graphics devices should be
reinstalled.
* Graphics devices should now specify deviceVersion to indicate
what version of the graphics engine they support.
* Graphics devices can now specify deviceClip. If TRUE, the
graphics engine will never perform any clipping of output itself.
The clipping that the graphics engine does perform (for both
canClip = TRUE and canClip = FALSE) has been improved to avoid
producing unnecessary artifacts in clipped output.
* The grid package now allows gpar(fill) to be a linearGradient(),
a radialGradient(), or a pattern(). The viewport(clip) can now
also be a grob, which defines a clipping path, and there is a new
viewport(mask) that can also be a grob, which defines a mask.
These new features are only supported so far on the Cairo-based
graphics devices and on the pdf() device.
* (Not Windows.) A warning is given when a Cairo-based type is
specified for a png(), jpeg(), tiff() or bmp() device but Cairo
is unsupported (so type = "Xlib" is tried instead).
* grSoftVersion() now reports the versions of FreeType and
FontConfig if they are used directly (not _via_ Pango), as is
most commonly done on macOS.
C-LEVEL FACILITIES:
* The _standalone_ libRmath math library and R's C API now provide
log1pexp() again as documented, and gain log1mexp().
INSTALLATION on a UNIX-ALIKE:
* configure checks for a program pkgconf if program pkg-config is
not found. These are now only looked for on the path (like
almost all other programs) so if needed specify a full path to
the command in PKG_CONFIG, for example in file config.site.
* C99 function iswblank is required - it was last seen missing ca
2003 so the workaround has been removed.
* There are new configure options --with-internal-iswxxxxx,
--with-internal-towlower and --with-internal-wcwidth which allows
the system functions for wide-character classification,
case-switching and width (wcwidth and wcswidth) to be replaced by
internal ones. The first has long been used on macOS, AIX (and
Windows) but this enables it to be unselected there and selected
for other platforms (it is the new default on Solaris). The
second is new in this version of R and is selected by default on
macOS and Solaris. The third has long been the default and
remains so as it contains customizations for East Asian
languages.
System versions of these functions are often minimally
implemented (sometimes only for ASCII characters) and may not
cover the full range of Unicode points: for example Solaris (and
Windows) only cover the Basic Multilingual Plane.
* Cairo installations without X11 are more likely to be detected by
configure, when the file-based Cairo graphics devices will be
available but not X11(type = "cairo").
* There is a new configure option --with-static-cairo which is the
default on macOS. This should be used when only static cairo
(and where relevant, Pango) libraries are available.
* Cairo-based graphics devices on platforms without Pango but with
FreeType/FontConfig will make use of the latter for font
selection.
LINK-TIME OPTIMIZATION on a UNIX-ALIKE:
* Configuring with flag --enable-lto=R now also uses LTO when
installing the recommended packages.
* R CMD INSTALL and R CMD SHLIB have a new flag --use-LTO to use
LTO when compiling code, for use with R configured with
--enable-lto=R. For R configured with --enable-lto, they have
the new flag --no-use-LTO.
Packages can opt in or out of LTO compilation _via_ a UseLTO
field in the DESCRIPTION file. (As usual this can be overridden
by the command-line flags.)
BUILDING R on Windows:
* for GCC >= 8, FC_LEN_T is defined in config.h and hence character
lengths are passed from C to Fortran in _inter alia_ BLAS and
LAPACK calls.
* There is a new text file src/gnuwin32/README.compilation, which
outlines how C/Fortran code compilation is organized and
documents new features:
* R can be built with Link-Time Optimization with a suitable
compiler - doing so with GCC 9.2 showed several
inconsistencies which have been corrected.
* There is support for cross-compiling the C and Fortran code
in R and standard packages on suitable (Linux) platforms.
This is mainly intended to allow developers to test later
versions of compilers - for example using GCC 9.2 or 10.x has
detected issues that GCC 8.3 in Rtools40 does not.
* There is experimental support for cross-building R packages
with C, C++ and/or Fortran code.
* The R installer can now be optionally built to support a single
architecture (only 64-bit or only 32-bit).
PACKAGE INSTALLATION:
* The default C++ standard has been changed to C++14 where
available (which it is on all currently checked platforms): if
not (as before) C++11 is used if available otherwise C++ is not
supported.
Packages which specify C++11 will still be installed using C++11.
C++14 compilers may give deprecation warnings, most often for
std::random_shuffle (deprecated in C++14 and removed in C++17).
Either specify C++11 (see 'Writing R Extensions') or modernize
the code and if needed specify C++14. The latter has been
supported since R 3.4.0 so the package's DESCRIPTION would need
to include something like
Depends: R (>= 3.4)
PACKAGE INSTALLATION on Windows:
* R CMD INSTALL and R CMD SHLIB make use of their flag --use-LTO
when the LTO_OPT make macro is set in file etc/${R_ARCH}/Makeconf
or in a personal/site Makevars file. (For details see 'Writing R
Extensions' SS4.5.)
This provides a valuable check on code consistency. It does work
with GCC 8.3 as in Rtools40, but that does not detect everything
the CRAN checks with current GCC do.
PACKAGE INSTALLATION on macOS:
* The default personal library directory on builds with
--enable-aqua (including CRAN builds) now differs by CPU type,
one of
~/Library/R/x86_64/x.y/library
~/Library/R/arm64/x.y/library
This uses the CPU type R (and hence the packages) were built for,
so when a x86_64 build of R is run under Rosetta emulation on an
arm64 Mac, the first is used.
UTILITIES:
* R CMD check can now scan package functions for bogus return
statements, which were possibly intended as return() calls (wish
of PR#17180, patch by Sebastian Meyer). This check can be
activated via the new environment variable
_R_CHECK_BOGUS_RETURN_, true for --as-cran.
* R CMD build omits tarballs and binaries of previous builds from
the top-level package directory. (PR#17828, patch by Sebastian
Meyer.)
* R CMD check now runs sanity checks on the use of LazyData, for
example that a data directory is present and that
LazyDataCompression is not specified without LazyData and has a
documented value. For packages with large LazyData databases
without specifying LazyDataCompression, there is a reference to
the code given in 'Writing R Extensions' SS1.1.6 to test the
choice of compression (as in all the CRAN packages tested a
non-default method was preferred).
* R CMD build removes LazyData and LazyDataCompression fields from
the DESCRIPTION file of packages without a data directory.
ENCODING-RELATED CHANGES:
* The parser now treats \Unnnnnnnn escapes larger than the upper
limit for Unicode points (\U10FFFF) as an error as they cannot be
represented by valid UTF-8.
Where such escapes are used for outputting non-printable
(including unassigned) characters, 6 hex digits are used (rather
than 8 with leading zeros). For clarity, braces are used, for
example \U{0effff}.
* The parser now looks for non-ASCII spaces on Solaris (as
previously on most other OSes).
* There are warnings (including from the parser) on the use of
unpaired surrogate Unicode points such as \uD834. (These cannot
be converted to valid UTF-8.)
* Functions nchar(), tolower(), toupper() and chartr() and those
using regular expressions have more support for inputs with a
marked Latin-1 encoding.
* The character-classification functions used (by default) to
replace the system iswxxxxx functions on Windows, macOS and AIX
have been updated to Unicode 13.0.0.
The character-width tables have been updated to include new
assignments in Unicode 13.0.0.
* The code for evaluating default (extended) regular expressions
now uses the same character-classification functions as the rest
of R (previously they differed on Windows, macOS and AIX).
* There is a build-time option to replace the system's
wide-character wctrans C function by tables shipped with R: use
configure option --with-internal-towlower or (on Windows)
-DUSE_RI18N_CASE in CFLAGS when building R. This may be needed
to allow tolower() and toupper() to work with Unicode characters
beyond the Basic Multilingual Plane where not supported by system
functions (e.g. on Solaris where it is the new default).
* R is more careful when truncating UTF-8 and other multi-byte
strings that are too long to be printed, passed to the system or
libraries or placed into an internal buffer. Truncation will no
longer produce incomplete multibyte characters.
DEPRECATED AND DEFUNCT:
* Function plclust() from the package stats and
package.dependencies(), pkgDepends(), getDepList(),
installFoundDepends(), and vignetteDepends() from package tools
are defunct.
* Defunct functions checkNEWS() and readNEWS() from package tools
and CRAN.packages() from utils have been removed.
* R CMD config CXXCPP is defunct (it was deprecated in R 3.6.2).
* parallel::detectCores() drops support for Irix (retired in 2013).
* The LINPACK argument to chol.default(), chol2inv(),
solve.default() and svd() has been defunct since R 3.1.0. It was
silently ignored up to R 4.0.3 but now gives an error.
* Subsetting/indexing, such as ddd[*] or ddd$x on a DOTSXP
(dot-dot-dot) object ddd has been disabled; it worked by accident
only and was undocumented.
BUG FIXES:
* Many more C-level allocations (mainly by malloc and strdup) are
checked for success with suitable alternative actions.
* Bug fix for replayPlot(); this was turning off graphics engine
display list recording if a recorded plot was replayed in the
same session. The impact of the bug became visible if resize the
device after replay OR if attempted another savePlot() after
replay (empty display list means empty screen on resize or empty
saved plot).
* R CMD check etc now warn when a package exports non-existing S4
classes or methods, also in case of no "methods" presence.
(Reported by Alex Bertram; reproducible example and patch by
Sebastian Meyer in PR#16662.)
* boxplot() now also accepts calls for labels such as ylab, the
same as plot(). (Reported by Marius Hofert.)
* The help page for xtabs() now correctly states that addNA is
setting na.action = na.pass among others. (Reported as PR#17770
by Thomas Soeiro.)
* The R CMD check <pkg> gives a longer and more comprehensible
message when DESCRIPTION misses dependencies, e.g., in Imports:.
(Thanks to the contributors of PR#17179.)
* update.default() now calls the generic update() on the formula to
work correctly for models with extended formulas. (As reported
and suggested by Neal Fultz in PR#17865.)
* The horizontal position of leaves in a dendrogram is now correct
also with center = FALSE. (PR#14938, patch from Sebastian
Meyer.)
* all.equal.POSIXt() no longer warns about and subsequently ignores
inconsistent "tzone" attributes, but describes the difference in
its return value (PR#17277). This check can be disabled _via_
the new argument check.tzone = FALSE as suggested by Sebastian
Meyer.
* as.POSIXct() now populates the "tzone" attribute from its tz
argument when x is a logical vector consisting entirely of NA
values.
* x[[2^31]] <- v now works. (Thanks to the report and patch by
Suharto Anggono in PR#17330.)
* In log-scale graphics, axis() ticks and label positions are now
computed more carefully and symmetrically in their range,
typically providing _more_ ticks, fulfilling wishes in PR#17936.
The change really corresponds to an improved axisTicks() (package
grDevices), potentially influencing grid and lattice, for
example.
* qnorm(<very large negative>, log.p=TRUE) is now correct to at
least five digits where it was catastrophically wrong,
previously.
* sum(df) and similar "Summary"- and "Math"-group member functions
now work for data frames df with logical columns, notably also of
zero rows. (Reported to R-devel by Martin "b706".)
* unsplit() had trouble with tibbles due to unsound use of rep(NA,
len)-indexing, which should use NA_integer_ (Reported to R-devel
by Mario Annau.)
* pnorm(x, log.p = TRUE) underflows to -Inf slightly later.
* show(<hidden S4 generic>) prints better and without quotes for
non-hidden S4 generics.
* read.table() and relatives treated an "NA" column name as missing
when check.names = FALSE PR#18007.
* Parsing strings containing UTF-16 surrogate pairs such as
"\uD834\uDD1E" works better on some (uncommon) platforms.
sprintf("%X", utf8ToInt("\uD834\uDD1E")) should now give "1D11E"
on all platforms.
* identical(x,y) is no longer true for differing DOTSXP objects,
fixing PR#18032.
* str() now works correctly for DOTSXP and related exotics, even
when these are doomed.
Additionally, it no longer fails for lists with a class and
"irregular" method definitions such that e.g. lapply(*) will
necessarily fail, as currently for different igraph objects.
* Too long lines in environment files (e.g. Renviron) no longer
crash R. This limit has been increased to 100,000 bytes.
(PR#18001.)
* There is a further workaround for FreeType giving incorrect
italic font faces with cairo-based graphics devices on macOS.
* add_datalist(*, force = TRUE) (from package tools) now actually
updates an existing data/datalist file for new content. (Thanks
to a report and patch by Sebastian Meyer in PR#18048.)
* cut.Date() and cut.POSIXt() could produce an empty last interval
for breaks = "months" or breaks = "years". (Reported as PR#18053
by Christopher Carbone.)
* Detection of the encoding of 'regular' macOS locales such as
en_US (which is UTF-8) had been broken by a macOS change:
fortunately these are now rarely used with en_US.UTF-8 being
preferred.
* sub() and gsub(pattern, repl, x, *) now keep attributes of x such
as names() also when pattern is NA (PR#18079).
* Time differences ("difftime" objects) get a replacement and a
rep() method to keep "units" consistent. (Thanks to a report and
patch by Nicolas Bennett in PR#18066.)
* The \RdOpts macro, setting defaults for \Sexpr options in an Rd
file, had been ineffective since R 2.12.0: it now works again.
(Thanks to a report and patch by Sebastian Meyer in PR#18073.)
* mclapply and pvec no longer accidentally terminate parallel
processes started before by mcparallel or related calls in
package parallel (PR#18078).
* grep and other functions for evaluating (extended) regular
expressions handle in Unicode also strings not explicitly flagged
UTF-8, but flagged native when running in UTF-8 locale.
* Fixed a crash in fifo implementation on Windows (PR#18031).
* Binary mode in fifo on Windows is now properly detected from
argument open (PR#15600, PR#18031).
# dplyr 1.0.6
* `add_count()` is now generic (#5837).
* `if_any()` and `if_all()` abort when a predicate is mistakingly used
as `.cols=` (#5732).
* Multiple calls to `if_any()` and/or `if_all()` in the same
expression are now properly disambiguated (#5782).
* `filter()` now inlines `if_any()` and `if_all()` expressions. This
greatly improves performance with grouped data frames.
* Fixed behaviour of `...` in top-level `across()` calls (#5813, #5832).
* `across()` now inlines lambda-formulas. This is slightly more performant and
will allow more optimisations in the future.
* Fixed issue in `bind_rows()` causing lists to be incorrectly transformed as
data frames (#5417, #5749).
* `select()` no longer creates duplicate variables when renaming a variable
to the same name as a grouping variable (#5841).
* `dplyr_col_select()` keeps attributes for bare data frames (#5294, #5831).
* Fixed quosure handling in `dplyr::group_by()` that caused issues with extra
arguments (tidyverse/lubridate#959).
* Removed the `name` argument from the `compute()` generic (@ianmcook, #5783).
* row-wise data frames of 0 rows and list columns are supported again (#5804).
# dplyr 1.0.5
* Fixed edge case of `slice_sample()` when `weight_by=` is used and there
0 rows (#5729).
* `across()` can again use columns in functions defined inline (#5734).
* Using testthat 3rd edition.
* Fixed bugs introduced in `across()` in previous version (#5765).
* `group_by()` keeps attributes unrelated to the grouping (#5760).
* The `.cols=` argument of `if_any()` and `if_all()` defaults to `everything()`.
# dplyr 1.0.4
* Improved performance for `across()`. This makes `summarise(across())` and
`mutate(across())` perform as well as the superseded colwise equivalents (#5697).
* New functions `if_any()` and `if_all()` (#4770, #5713).
* `summarise()` silently ignores NULL results (#5708).
* Fixed a performance regression in `mutate()` when warnings occur once per
group (#5675). We no longer instrument warnings with debugging information
when `mutate()` is called within `suppressWarnings()`.
# dplyr 1.0.3
* `summarise()` no longer informs when the result is ungrouped (#5633).
* `group_by(.drop = FALSE)` preserves ordered factors (@brianrice2, #5545).
* `count()` and `tally()` are now generic.
* Removed default fallbacks to lazyeval methods; this will yield
better error messages when you call a dplyr function with the wrong
input, and is part of our long term plan to remove the deprecated
lazyeval interface.
* `inner_join()` gains a `keep` parameter for consistency with the other
mutating joins (@patrickbarks, #5581).
* Improved performance with many columns, with a dynamic data mask using active
bindings and lazy chops (#5017).
* `mutate()` and friends preserves row names in data frames once more (#5418).
* `group_by()` uses the ungrouped data for the implicit mutate step (#5598).
You might have to define an `ungroup()` method for custom classes.
For example, see https://github.com/hadley/cubelyr/pull/3.
* `relocate()` can rename columns it relocates (#5569).
* `distinct()` and `group_by()` have better error messages when the
mutate step fails (#5060).
* Clarify that `between()` is not vectorised (#5493).
* Fixed `across()` issue where data frame columns would could not be referred to
with `all_of()` in the nested case (`mutate()` within `mutate()`) (#5498).
* `across()` handles data frames with 0 columns (#5523).
* `mutate()` always keeps grouping variables, unconditional to `.keep=` (#5582).
* dplyr now depends on R 3.3.0
# dplyr 1.0.2
* Fixed `across()` issue where data frame columns would mask objects referred to
from `all_of()` (#5460).
* `bind_cols()` gains a `.name_repair` argument, passed to
`vctrs::vec_cbind()` (#5451)
* `summarise(.groups = "rowwise")` makes a rowwise data frame even if
the input data is not grouped (#5422).
# dplyr 1.0.1
* New function `cur_data_all()` similar to `cur_data()` but includes
the grouping variables (#5342).
* `count()` and `tally()` no longer automatically weights by column `n` if
present (#5298). dplyr 1.0.0 introduced this behaviour because of Hadley's
faulty memory. Historically `tally()` automatically weighted and `count()`
did not, but this behaviour was accidentally changed in 0.8.2 (#4408) so that
neither automatically weighted by `n`. Since 0.8.2 is almost a year old,
and the automatically weighting behaviour was a little confusing anyway,
we've removed it from both `count()` and `tally()`.
Use of `wt = n()` is now deprecated; now just omit the `wt` argument.
* `coalesce()` now supports data frames correctly (#5326).
* `cummean()` no longer has off-by-one indexing problem (@cropgen, #5287).
* The call stack is preserved on error. This makes it possible to `recover()`
into problematic code called from dplyr verbs (#5308).
These produce poor code and it's always better to use the CPU-specific
intrinsics instead, which we already do on platforms where the test
suite doesn't fail.
Those cmake config files are not useful for us and they are incorrect
for the upcoming 64-bit-index variants. Also, we could switch back
to the Makefile build from cmake in future. Let's treat the question of
CMake as implementation detail of the packages.
The actual use is via mk/blas.bl3 in pkgsrc and pkg-config. There isn't
even added value in these files, were they to be correct. CMake builds
can use pkg-config just fine.
Changed in xts 0.12.1:
o Various function could change the tclass of xts objects. This would happen
in calls to reclass(), period.apply(), and for logical operations on
POSIXct indexes. Thanks to Tom Andrews for the report and testing, and to
Panagiotis Cheilaris for contributing test cases (#322, #323).
o plot.xts() now supports y-axis labels via 'ylab'. Thanks to Jasen Mackie
for the suggestion and PR (#333, #334).
o The API header has been updated to fix the signatures of do_merge_xts() and
is_xts, which did not return a SEXP as required of functions callable by
.Call(). Thanks to Tomas Kalibera for the report (#317), and Dirk
Eddelbuettel for the PR (#337). This is a breaking change, but is required
to avoid the potential for a segfault.
o Michael Chirico added an internal isUTC() function to recognize many UTC-
equivalent time zones (#319).
o first() now operates correctly on non-xts objects when 'n = -1'. Previously
it would always return the last two values. Thanks to GitHub user vxg20
for the report (#325).
o The .xts() constructor would create an xts object with row names if 'x' had
row names. This shouldn't happen, because xts objects do not have or
support row names (#298).
o Claymore Marshall added many examples of time-of-day subsetting to
?subset.xts. He also fixed a bug in time-of-day subsetting where subsetting
by hour only returned wrong results (#304, #326, #328).
Changed in xts 0.12-0:
o All the index-attributes have been removed from the xts object and are now
only attached to the index itself (#245). We took great care to maintain
backward compatibility, and throw warnings when deprecated functions are
called and when index-attributes are found on the xts object. But there
still may be some breaking changes lurking in edge cases.
o @SamoPP found one edge case (#297) where an error was thrown when index()
was called on an xts object with an index that had no tclass attribute.
o ...which led Joshua to find that the index setting functions did not
always copy index attributes (#305).
o Several binary operations (e.g. +, -, !=, <, etc.) on variations of
uncommon xts objects with other xts, matrix, or vector objects, could
result in malformed xts objects (#295). Some examples of the types of
uncommon xts objects: no dim attribute, zero-width, zero-length.
o Calling as.matrix() on an xts object without a dim attribute no longer
throws an error (#294).
o merge.xts() now honors check.names = FALSE (#293).
o The possible values for major.ticks, minor.ticks, and grid.ticks.on in the
Details section of ?plot.xts have been corrected. Thanks to Harvey Smith
(@harvey131) for the report and patch (#291).
o as.zoo.xts() is now only registered for zoo versions prior to 1.8-5. Methods
to convert an object to another class should reside in the package that
implements the target class. Thanks to Kurt Hornik for the report (#287).
o .parseISO8601() no longer has a potential length-1 logical error. Thanks to
Kurt Hornik for the report (#280).
o endpoints() now honors k > 0 when on = "quarters". Thanks to @alkment for
the report (#279).
o Performance for the period.XYZ() functions (sum, prod, min, max) is much
faster (#278). Thanks to Harvey Smith (@harvey131) for the report and
examples.
o merge.xts() now creates shorter column names when passed unnamed objects.
This is now consistent with zoo (#248).
o Time-of-day performance is ~200x faster, thanks to StackOverflow
user3226167 (#193).
Changes in Version 1.8-9
o Added a basic boxplot(x, ...) method for zoo objects that simply calls
boxplot(coredata(x), ...).
o Bug fix in [.zoo and [<-.zoo where indexing with matrices did not
work correctly anymore in R 4.x.y because "matrix" objects now additionally
inherit from "array" objects. (Reported by Bill Cunliffe.)
o Improved internal functionality in na.spline.default() in the same way
na.approx.default() was enhanced in zoo 1.7-14 and 1.7-13. One difference
is that while na.approx() requires at least two non-NA observations,
na.spline() just needs one non-NA observation (using a constant to
interpolate in that case).
o If the FUN in rollapply() returns a matrix or data.frame with more than
one row per element/time point, then this is flattened now so that the
result is again a matrix with one row per element/time point.
o merge.zoo() now handles the case of all indexes being integer or numeric
by coercing the integer indexes to numeric (reported by Simone Giannerini).
o zooreg(x) now allows to create an integer index if start (and end, if any)
are integer and the implied deltat is not numerically different from an
integer value.
Changes in Version 1.8-8
o diff.zoo(x, arithmetic = FALSE) now also works if x contains negative
data.
o merge.zoo() now handles the combination of Date and numeric indexes
explicitly to work around the new behavior of c.Date() in R >= 4.1.0.
Changes in Version 1.8-7
o Added scale_type() methods for yearmon/yearqtr to facilitate ggplot2
visualizations of zoo series with yearmon/yearqtr time index (suggested
by Brian Diggs). This requires at least ggplot2 3.0.0.
o In merge.zoo() "character" columns are now processed in the same way
as "logical" columns.
o Replaced the "fruitohms" example in the "zoo" vignette because the
corresponding "DAAG" package is not actively maintained on CRAN anymore.
Instead the "Journals" data from the "AER" package is used.
# forcats 0.5.1
* Re-license as MIT (#277).
* `fct_lump_n()` no longer uses a partial argument name (@malcolmbarrett, #276).
# forcats 0.5.0
* `as_factor()` gains a logical method that always returns a factor with
levels "FALSE" and "TRUE" (#185).
* `fct_c()`, `fct_collapse()` and `fct_recode()` are now explicitly
documented as using [dynamic dots](https://rlang.r-lib.org/reference/dyn-dots.html)
(@labouz, #234).
* `fct_collapse()` now accepts a `other_level` argument, to allow a
user-specified `Other` level (@gtm19, #194). It now correctly collapses
factors when `other_level` is not `NULL` (#172), and makes `"Other"` the
last level (#202) (@gtm19, #172 & #202)
* `fct_count()` no longer converts implicit NAs into explicit NAs (#151).
* `fct_inseq()` behaves more robustly when factor levels aren't all numbers
(#221).
* `fct_lump()` has been split up into three new functions: `fct_lump_prop()`,
`fct_lump_n()`, and `fct_lump_lowfreq()`. (@jonocarroll, #167, #142).
All `fct_lump_()` functions check their inputs more carefully
(@robinson_es, #169)
* `fct_reorder2()` gains a helper function `first2()`, that sorts `.y` by the
first value of `.x` (@jtr13).

# tibble 3.1.2
- Bump required versions of ellipsis and vctrs to avoid warning during package load.
# tibble 3.1.1
- `num()` and `char()` are reexported from pillar (#880).

## Bug fixes
- `has_rownames()` now works correctly for data frames with a `"row.names"` attribute malformed due to a problem in `structure()` (#852).
- `tbl[FALSE, "column"] <- x` adds new column again (#846).
## Features
- Importing pillar 1.5.0, cli and crayon are now suggested packages (#475).
- `size_sum()` is now reexported from pillar (#850, @topepo).
- `as_tibble()` hints more often to use the `.name_repair` argument if column names are invalid (#855).
- `as_tibble.table()` mentions `.name_repair` argument in the error message (#839).
## Internal
- Remove compatibility code for pillar < 1.5.0 (#861).
- Moved most functions to the "stable" lifecycle (#860).
# tibble 3.0.6
- `vec_ptype_abbr.tbl_df()` and `type_sum.tbl_df()` now uses the name of the topmost class for subclasses of `"tbl_df"` (#843).
- Ignore errors in `formats.Rmd` vignette.
- Avoid tidy evaluation in pillar compatibility code.
# tibble 3.0.5
- Use testthat edition 3, compatible with testthat 3.0.1 (#827, #832).
# tibble 3.0.4
## Compatibility
- Establish compatibility with upcoming pillar 1.5.0 (#818).
- `tbl_sum()` shows "data frame" instead of "tibble" for objects inheriting from `"tbl"` but not `"tbl_df"` (#818).
- Register `format.tbl()` and `print.tbl()` methods only if pillar doesn't (#816).
- Use `vctrs::num_as_location()` internally for subset assignment of rows and columns for better error messages (#746).
- Adapt tests to the development version of testthat.
## Bug fixes
- Fix documentation link to `base::Extract`.
- `add_row(df)` adds an empty row again (#809, @DavisVaughan).
# tibble 3.0.3
- Fix test compatibility with rlang 0.4.7.

# tibble 3.0.2
## Bug fixes
- `[[` works with classed indexes again, e.g. created with `glue::glue()` (#778).
- `add_column()` works without warning for 0-column data frames (#786).
- `tribble()` now better handles named inputs (#775) and objects of non-vtrs classes like `lubridate::Period` (#784) and `formattable::formattable` (#785).
## Performance
- Subsetting and subassignment are faster (#780, #790, #794).
- `is.null()` is preferred over `is_null()` for speed.
- Implement continuous benchmarking (#793).
## Compatibility
- `is_vector_s3()` is no longer reexported from pillar (#789).
# tibble 3.0.1
## Compatibility fixes
- `[<-.tbl_df()` coerces matrices to data frames (#762).
- Use delayed import for cli to work around unload problems in downstream packages (#754).
## Bug fixes
- More soft-deprecation warnings are actually visible.
- If `.name_repair` is a function, no repair messages are shown (#763).
- Remove superseded signal for `as_tibble.list()`, because `as_tibble_row()` only works for size 1.
## Enhancements
- `as_tibble(validate = )` now always triggers a deprecation warning.
- Subsetting and subassignment of rows with one-column matrices work again, with a deprecation warning (#760).
- Attempts to update a tibble row with an atomic vector give a clearer error message. Recycling message for subassignment appears only if target size is != 1.
- Tweak title of "Invariants" vignette.
# tibble 3.0.0
## Major breaking changes
- Subset assignment ("subassignment") and also subsetting has become stricter. Symptoms:
- Error: No common type for ...
- Error: Assigned data `...` must be compatible with ...
- `i` must have one dimension, not 2
- Error: Lossy cast from ... to ...
The "invariants" article at https://tibble.tidyverse.org/dev/articles/invariants.html describes the invariants that the operations follow in tibble, and the most important differences to data frames. We tried to make subsetting and subassignment as safe as possible, so that errors are caught early on, while introducing as little friction as possible.
- List classes are no longer automatically treated as vectors. Symptoms:
- Error: All columns in a tibble must be vectors
- Error: Expected a vector, not a `...` object
If you implement a class that wraps a list as S3 vector, you need to include `"list"` in the class:
```r
structure(x, class = c("your_s3_class", "list"))
```
Alternatively, implement a `vec_proxy()` method as described in https://vctrs.r-lib.org/reference/vec_data.html, or construct your class with `list_of()`.
- Added experimental support for inner names for all columns, of the form `tibble(a = c(b = 1))`. Inner names are no longer stripped when creating a tibble. They are maintained for slicing operations but not yet updated when assigning with a row subscript. This is a change that may break existing comparison tests that don't expect names in columns (#630). Symptoms:
- "names for target but not for current" when comparing
## Breaking changes
- `tibble()` now splices anonymous data frames, `tibble(tibble(a = 1), b = a)` is equivalent to `tibble(a = 1, b = a)`. This means that `tibble(iris)` now has five columns, use `tibble(iris = iris)` if the intention is to create a packed data frame (#581).
- The `name-repair` help topic is gone, refer to `?vctrs::vec_as_names` instead.
- `expression()` columns are converted to lists as a workaround for lacking support in vctrs (#657).
- `tribble()` is now stricter when combining values. All values in a column must be compatible, otherwise an error occurs (#204). The criteria for wrapping in a list column are now based on vctrs principles: non-vectors or vectors with `vctrs::vec_size()` unequal 1 are wrapped in lists.
- `$` warns unconditionally if column not found, `[[` doesn't warn.
- `add_row()` now uses `vctrs::vec_rbind()` under the hood, this means that all columns are combined with `vctrs::vec_c()`. In particular, factor columns will be converted to character if one of the columns is a character column.
## Soft deprecations
- Soft-deprecate `subclass` argument to `new_tibble()`.
- Soft-deprecate `as_tibble()` without arguments (#683).
- Preparing to move `glimpse()` and `tbl_sum()` to the pillar package. If your package implements these methods, please import the generics from pillar as soon as they become available there.
## Features
- Internals now make heavy use of the vctrs package, following most of the invariants defined there. Name repair is the responsibility of vctrs now (#464).
- All errors emitted directly by the package inherit from the `"tibble_error"` and `"rlang_error"` classes. In some cases, `"vctrs_error"` errors may be passed through. The exact subclass is subject to change.
Example: `tibble(a = quote(b))` raises an error that inherits from `"tibble_error_column_must_be_vector"`, `"tibble_error"` and `"rlang_error"`, and from `"error"` and `"condition"` like all errors. Do not rely on the wording of `"tibble_error_column_must_be_vector"`, this is likely to change.
Use the following pattern to catch errors emitted by tibble:
```r
tryCatch(
your_code(),
tibble_error = function(cnd) {
}
)
```
- New `tibble_row()` constructs tibbles that have exactly one row, or fails. Non-vector objects are automatically wrapped in a list, vectors (including lists) must have length one (#205).
- New `as_tibble_row()` and `as_tibble_col()` convert a bare vector to a one-row or one-column tibble, respectively. `as_tibble_col()` also works for non-bare vectors. Using `as_tibble()` for bare vectors is superseded (#447).
- `as_tibble.data.frame()` uses implicit row names if asked to create a column from row names. This allows lossless direct conversion of matrices with row names to tibbles (#567, @stufield).
- Implement `str.tbl_df()` (#480).
- `tribble()` now returns columns with `"unspecified"` type for 0-row tibbles.
- `add_row()` and `add_column()` now restore attributes to avoid errors when appending to sf objects or other tibble subclasses (#662).
- `add_column()` gains `.name_repair` argument. If not given, `.data` must have unique columns, with a deprecation message.
- Allow `POSIXlt` columns, they are now better supported by dplyr and other tools thanks to vctrs (#626).
- `tibble()` ignores NULL arguments, named or unnamed (#580).
- `view()` works for remote data sources by applying the same strategy as `print()` and `glimpse()`. The maximum number of rows in this case can be specified using the new `n` argument, by default it is taken from the new `"tibble.view_max"` option (#695).
## Output
- Formatting dimensions never uses scientific notation.
- `glimpse()` uses "Rows" and "Columns" instead of "Variables" and "Observations", because we're not sure if the data is tidy here (#614).
- `view()` now uses the created (or passed) title argument (#610, @xvrdm).
## Performance
- Construction and subsetting of large data frames is faster now (#717, @romainfrancois).
## Internal
- Import lifecycle package (#669).
- `new_tibble()` removes redundant subclasses from the `"class"` attribute.
- Using classed conditions. All classes start with `"tibble_error_"` and also contain `"tibble_error"` (#659).
- The magrittr pipe `%>%` is reexported.
# 1.1.1
* Fix spurious zero fractions in `pretty_bytes()` when formatting
vectors of sizes (#23).
# 1.1.0
* `pretty_dt()`, `pretty_ms()` and `pretty_sec()` now handle `NA` values
properly, and return `NA_character_` for them (#10, @petermeissner).
* `pretty_bytes()` now formats quantities just below the units better.
E.g. 1MB - 1B is formatted as `"1 MB"` instead of `""1000 kB"` (#18).
* `pretty_bytes()` now has multiple styles. In particular, a fixed width
style is useful for progress bars. Another style avoids the left-padding
with spaces.
* The new low level `compute_bytes()` function can be used to create
custom formatters for bytes.
This also affects py-{ailment,archinfo,cle,pyvex,claripy}, which get updated to
the same version at the same time.
I could not find any specific release notes or changelog.

The upcoming lapack64 needs the library name liblapack64, the
variable for that was missing in the patch. This does not change
the build of math/lapack itself.
* What is new in gsl-2.6:
** add BLAS calls for the following functions:
- gsl_vector_memcpy
- gsl_vector_scale
- gsl_matrix_memcpy
- gsl_matrix_transpose_memcpy
- gsl_matrix_tricpy
- gsl_matrix_transpose_tricpy
** deprecated functions gsl_linalg_complex_householder_hm and
gsl_linalg_complex_householder_mh
** add unit tests for gsl_linalg_symmtd and gsl_linalg_hermtd
** multilarge TSQR algorithm has been converted to use the new Level 3 QR decomposition
** nonlinear least squares Cholesky solver now uses the new Level 3 BLAS
method; the old modified Cholesky solver is still available under
gsl_multifit_nlinear_solver_mcholesky and gsl_multilarge_nlinear_solver_mcholesky
** implemented Level 3 BLAS versions of several linear algebra routines:
- Triangular matrix inversion
- Cholesky decomposition and inversion (real and complex)
- LU decomposition and inversion (real and complex)
- QR decomposition (courtesy of Julien Langou)
- Generalized symmetric/hermitian eigensystem reduction to standard form
** removed deprecated function gsl_linalg_hessenberg()
** renamed gsl_interp2d_eval_e_extrap() to gsl_interp2d_eval_extrap_e()
to match documentation (reported by D. Lebrun-Grandie)
** renamed some of the gsl_sf_hermite functions to be more consistent
with rest of the library, and deprecated old function names
** updated gsl_sf_hermite_func() to use a newer algorithm
due to B. Bunck which is more stable for large x; also added
gsl_sf_hermite_func_fast() which uses the faster Cauchy integral
algorithm in the same paper by Bunck
** add gsl_vector_axpby()
** add un-pivoted LDLT decomposition and its banded
variant (gsl_linalg_ldlt_* and gsl_linalg_ldlt_band_*)
** add binary search tree module (gsl_bst); based on GNU libavl
** remove -u flag to gsl-histogram
** updated spmatrix module
- added routines and data structures for all types (float,uint,char,...)
- added gsl_spmatrix_scale_columns() and gsl_spmatrix_scale_rows()
- added gsl_spmatrix_add_to_dense()
- more efficient reallocation of COO/triplet matrices (no longer rebuilds binary tree)
- enhanced test suite
- added gsl_spmatrix_min_index()
** add routines for banded Cholesky decomposition (gsl_linalg_cholesky_band_*)
** documented gsl_linalg_LQ routines and added gsl_linalg_LQ_lssolve()
This updates octave and also gets some more recommened dependencies in,
namely qrupdate and Mesalib (for osmesa) and gl2ps as well as the
qscintilla editor. The glpk option is on by default again.
This version of octave comes rather close to a standard build, with
optimzied BLAS and GUI fluff. We are still missing SuiteSparse and
SUNDIALS solvers, see
https://octave.org/doc/v6.2.0/External-Packages.html
PortAudio should also be considered, and LLVM be watched if that
experimental JIT settles in.
Upstream changes since 5.x:
Summary of important user-visible changes for version 6.1.0 (2020-11-26):
------------------------------------------------------------------------
### General improvements
- The `intersect`, `setdiff`, `setxor`, `union`, and `unique` functions
accept a new sorting option `"stable"` which will return output values
in the same order as the input, rather than in ascending order.
- Complex RESTful web services can now be accessed by the `webread` and
`webwrite` functions alongside with the `weboptions` structure. One
major feature is the support for cookies to enable RESTful
communication with the web service.
Additionally, the system web browser can be opened by the `web`
function.
- The `linspace` function now produces symmetrical sequences when the
endpoints are symmetric. This is more intuitive and also compatible
with recent changes made in Matlab R2019b.
- The underlying algorithm of the `rand` function has been changed.
For single precision outputs, the algorithm has been fixed so that it
produces values strictly in the range (0, 1). Previously, it could
occasionally generate the right endpoint value of 1 (See bug #41742).
In addition, the new implementation uses a uniform interval between
floating point values in the range (0, 1) rather than targeting a
uniform density (# of random integers / length along real number
line).
- Numerical integration has been improved. The `quadv` function has
been re-written so that it can compute integrands of periodic
functions. At the same time, performance is better with ~3.5X fewer
function evaluations required. A bug in `quadgk` that caused complex
path integrals specified with `"Waypoints"` to occasionally be
calculated in the opposite direction was fixed.
- The `edit` function option `"editinplace"` now defaults to `true` and
the option `"home"` now defaults to the empty matrix `[]`. Files will
no longer be copied to the user's HOME directory for editing. The old
behavior can be restored by setting `"editinplace"` to `false` and
`"home"` to `"~/octave"`.
- The `format` command supports two new options: `uppercase` and
`lowercase` (default). With the default, print a lowercase 'e' for
the exponent character in scientific notation and lowercase 'a-f' for
the hex digits representing 10-15. With `uppercase`, print 'E' and
'A-F' instead. The previous uppercase formats, `E` and `G`, no longer
control the case of the output.
Additionally, the `format` command can be called with multiple options
for controlling the format, spacing, and case in arbitrary order.
For example:
format long e uppercase loose
Note, in the case of multiple competing format options the rightmost
one is used, and, in case of an error, the previous format remains
unchanged.
- L-value references (e.g., increment (++), decrement (--), and all
in-place assignment operators (+=, -=, *=, /=, etc.)) are no longer
allowed in anonymous functions.
- New warnings have been added about questionable uses of the colon ':'
range operator. Each has a new warning ID so that it can be disabled
if desired.
> `Octave:colon-complex-argument` : when any arg is complex
> `Octave:colon-nonscalar-argument` : when any arg is non-scalar
- The `regexp` and related functions now correctly handle and *require*
strings in UTF-8 encoding. As with any other function that requires
strings to be encoded in Octave's native encoding, you can use
`native2unicode` to convert from your preferred locale. For example,
the copyright symbol in UTF-8 is `native2unicode (169, "latin1")`.
- The startup file `octaverc` can now be located in the platform
dependent location for user local configuration files (e.g.,
${XDG_CONFIG_HOME}/octave/octaverc on Unix-like operating systems or
%APPDATA%\octave\octaverc on Windows).
- `pkg describe` now lists dependencies and inverse dependencies
(i.e., other installed packages that depend on the package in
question).
- `pkg test` now tests all functions in a package.
- When unloading a package, `pkg` now checks if any remaining loaded
packages depend on the one to be removed. If this is the case `pkg`
aborts with an explanatory error message. This behavior can be
overridden with the `-nodeps` option.
- The command
dbstop in CLASS at METHOD
now works to set breakpoints in classdef constructors and methods.
#### Graphics backend
- The use of Qt4 for graphics and the GUI is deprecated in Octave
version 6 and no further bug fixes will be made. Qt4 support will be
removed completely in Octave version 7.
- The `legend` function has been entirely rewritten. This fixes a
number of historical bugs, and also implements new properties such as
`"AutoUpdate"` and `"NumColumns"`. The gnuplot toolkit---which is no
longer actively maintained---still uses the old legend function.
- The `axis` function was updated which resolved 10 bugs affecting
axes to which `"equal"` had been applied.
- Graphic primitives now accept a color property value of `"none"`
which is useful when a particular primitive needs to be hidden
(for example, the Y-axis of an axes object with `"ycolor" = "none"`)
without hiding the entire primitive `"visibility" = "off"`.
- A new property `"FontSmoothing"` has been added to text and axes
objects that controls whether anti-aliasing is used during the
rendering of characters. The default is `"on"` which produces smooth,
more visually appealing text.
- The figure property `"windowscrollwheelfcn"`is now implemented.
This makes it possible to provide a callback function to be executed
when users manipulate the mouse wheel on a given figure.
- The figure properties `"pointer"`, `"pointershapecdata"`, and
`"pointershapehotspot"` are now implemented. This makes it possible
to change the shape of the cursor (pointer in Matlab-speak) displayed
in a plot window.
- The figure property `"paperpositionmode"` now has the default `"auto"`
rather than `"manual"`. This change is more intuitive and is
Matlab compatible.
- The appearance of patterned lines `"LineStyle" = ":"|"--"|"-."` has
been improved for small widths (`"LineWidth"` less than 1.5 pixels)
which is a common scenario.
- Printing to EPS files now uses a tight bounding box (`"-tight"`
argument to print) by default. This makes more sense for EPS
files which are normally embedded within other documents, and is
Matlab compatible. If necessary use the `"-loose"` option to
reproduce figures as they appeared in previous versions of Octave.
- The following print devices are no longer officially supported: cdr,
corel, aifm, ill, cgm, hpgl, mf and dxf. A warning will be thrown
when using those devices, and the code for supporting those formats
will eventually be removed from a future version of Octave.
- The placement of text subscripts and superscripts has been
re-engineered and now produces visually attractive results similar to
Latex.
### Matlab compatibility
- The function `unique` now returns column index vectors for the second
and third outputs. When duplicate values are present, the default
index to return is now the `"first"` occurrence. The previous Octave
behavior, or Matlab behavior from releases prior to R2012b, can be
obtained by using the `"legacy"` flag.
- The function `setdiff` with the `"rows"` argument now returns Matlab
compatible results. The previous Octave behavior, or Matlab behavior
from releases prior to R2012b, can be obtained by using the `"legacy"`
flag.
- The functions `intersect`, `setxor`, and `union` now accept a
`"legacy"` flag which changes the index values (second and third
outputs) as well as the orientation of all outputs to match Matlab
releases prior to R2012b.
- The function `streamtube` is Matlab compatible and plots tubes along
streamlines which are scaled by the vector field divergence. The
Octave-only extension `ostreamtube` can be used to visualize the flow
expansion and contraction of the vector field due to the local
crossflow divergence.
- The interpreter now supports handles to nested functions.
- The graphics properties `"LineWidth"` and `"MarkerSize"` are now
measured in points, *not* pixels. Compared to previous versions
of Octave, some lines and markers will appear 4/3 larger.
- The meta.class property "SuperClassList" has been renamed
"Superclasslist" for Matlab compatibility. The original name will
exist as an alias until Octave version 8.1.
- Inline functions created by the function `inline` are now of type
"inline" when interrogated with the `class` function. In previous
versions of Octave, the class returned was "function_handle". This
change is Matlab compatible. Inline functions are deprecated in
both Matlab and Octave and support may eventually be removed.
Anonymous functions can be used to replace all instances of inline
functions.
- The function `javaaddpath` now prepends new directories to the
existing dynamic classpath by default. To append them instead, use
the new `"-end"` argument. Multiple directories may now be specified
in a cell array of strings.
- An undocumented function `gui_mainfcn` has been added, for compatibility
with figures created with Matlab's GUIDE.
- Several validator functions of type `mustBe*` have been added. See
the list of new functions below.

`runtests` | `oruntests`
- Properties
Object | Property | Value
-----------------|---------------|------------

- The environment variable used by `mkoctfile` for linker flags is now
`LDFLAGS` rather than `LFLAGS`. `LFLAGS` is deprecated, and a warning
is emitted if it is used, but it will continue to work.

It is wrong to disable OpenMP and this setting does nothing anyway.
Maybe it did in the past. Now, the build tries to use OpenMP if
possible and this is the right thing to do.
Repeat: This change doesn't affect the build at all since that variable
is not checked (since some time?).
(pkgsrc changes)
- Add TEST_DEPENDS+, but still one missing is there
(upstream changes)
# vctrs 0.3.8
* Compatibility with next version of rlang.
# vctrs 0.3.7
* `vec_ptype_abbr()` gains arguments to control whether to indicate
named vectors with a prefix (`prefix_named`) and indicate shaped
vectors with a suffix (`suffix_shape`) (#781, @krlmlr).
* `vec_ptype()` is now an optional _performance_ generic. It is not necessary
to implement, but if your class has a static prototype, you might consider
implementing a custom `vec_ptype()` method that returns a constant to
improve performance in some cases (such as common type imputation).
* New `vec_detect_complete()`, inspired by `stats::complete.cases()`. For most
vectors, this is identical to `!vec_equal_na()`. For data frames and
matrices, this detects rows that only contain non-missing values.
* `vec_order()` can now order complex vectors (#1330).
* Removed dependency on digest in favor of `rlang::hash()`.
* Fixed an issue where `vctrs_rcrd` objects were not being proxied correctly
when used as a data frame column (#1318).
* `register_s3()` is now licensed with the "unlicense" which makes it very
clear that it's fine to copy and paste into your own package
(@maxheld83, #1254).
# vctrs 0.3.6
* Fixed an issue with tibble 3.0.0 where removing column names with
`names(x) <- NULL` is now deprecated (#1298).
* Fixed a GCC 11 issue revealed by CRAN checks.
# vctrs 0.3.5
* New experimental `vec_fill_missing()` for filling in missing values with
the previous or following value. It is similar to `tidyr::fill()`, but
also works with data frames and has an additional `max_fill` argument to
limit the number of sequential missing values to fill.
* New `vec_unrep()` to compress a vector with repeated values. It is very
similar to run length encoding, and works nicely alongside `vec_rep_each()`
as a way to invert the compression.
* `vec_cbind()` with only empty data frames now preserves the common size of
the inputs in the result (#1281).
* `vec_c()` now correctly returns a named result with named empty inputs
(#1263).
* vctrs has been relicensed as MIT (#1259).
* Functions that make comparisons within a single vector, such as
`vec_unique()`, or between two vectors, such as `vec_match()`, now
convert all character input to UTF-8 before making comparisons (#1246).
* New `vec_identify_runs()` which returns a vector of identifiers for the
elements of `x` that indicate which run of repeated values they fall in
(#1081).
* Fixed an encoding translation bug with lists containing data frames which
have columns where `vec_size()` is different from the low level
`Rf_length()` (#1233).
# vctrs 0.3.4
* Fixed a GCC sanitiser error revealed by CRAN checks.
# vctrs 0.3.3
* The `table` class is now implemented as a wrapper type that
delegates its coercion methods. It used to be restricted to integer
tables (#1190).
* Named one-dimensional arrays now behave consistently with simple
vectors in `vec_names()` and `vec_rbind()`.
* `new_rcrd()` now uses `df_list()` to validate the fields. This makes
it more flexible as the fields can now be of any type supported by
vctrs, including data frames.
* Thanks to the previous change the `[[` method of records now
preserves list fields (#1205).
* `vec_data()` now preserves data frames. This is consistent with the
notion that data frames are a primitive vector type in vctrs. This
shouldn't affect code that uses `[[` and `length()` to manipulate
the data. On the other hand, the vctrs primitives like `vec_slice()`
will now operate rowwise when `vec_data()` returns a data frame.
* `outer` is now passed unrecycled to name specifications. Instead,
the return value is recycled (#1099).
* Name specifications can now return `NULL`. The names vector will
only be allocated if the spec function returns non-`NULL` during the
concatenation. This makes it possible to ignore outer names without
having to create an empty names vector when there are no inner
names:
```
zap_outer_spec <- function(outer, inner) if (is_character(inner)) inner
# `NULL` names rather than a vector of ""
names(vec_c(a = 1:2, .name_spec = zap_outer_spec))
#> NULL
# Names are allocated when inner names exist
names(vec_c(a = 1:2, c(b = 3L), .name_spec = zap_outer_spec))
#> [1] "" "" "b"
```
* Fixed several performance issues in `vec_c()` and `vec_unchop()`
with named vectors.
* The restriction that S3 lists must have a list-based proxy to be considered
lists by `vec_is_list()` has been removed (#1208).
* New performant `data_frame()` constructor for creating data frames in a way
that follows tidyverse semantics. Among other things, inputs are recycled
using tidyverse recycling rules, strings are never converted to factors,
list-columns are easier to create, and unnamed data frame input is
automatically spliced.
* New `df_list()` for safely and consistently constructing the data structure
underlying a data frame, a named list of equal-length vectors. It is useful
in combination with `new_data_frame()` for creating user-friendly
constructors for data frame subclasses that use the tidyverse rules for
recycling and determining types.
* Fixed performance issue with `vec_order()` on classed vectors which
affected `dplyr::group_by()` (tidyverse/dplyr#5423).
* `vec_set_names()` no longer alters the input in-place (#1194).
* New `vec_proxy_order()` that provides an ordering proxy for use in
`vec_order()` and `vec_sort()`. The default method falls through to
`vec_proxy_compare()`. Lists are special cased, and return an integer
vector proxy that orders by first appearance.
* List columns in data frames are no longer comparable through `vec_compare()`.
* The experimental `relax` argument has been removed from
`vec_proxy_compare()`.
Ellipsis 0.3.2
* Compatibility with next version of rlang.
* Changed license to MIT (#39).

v0.18.2 (19 May 2021)
---------------------
This release reverts a regression in xarray's unstacking of dask-backed arrays.
v0.18.1 (18 May 2021)
---------------------
This release is intended as a small patch release to be compatible with the new
2021.5.0 ``dask.distributed`` release. It also includes a new
``drop_duplicates`` method, some documentation improvements, the beginnings of
our internal Index refactoring, and some bug fixes.
New Features
- Implement :py:meth:`DataArray.drop_duplicates`
to remove duplicate dimension values (:pull:`5239`).
- Allow passing ``combine_attrs`` strategy names to the ``keep_attrs`` parameter of
:py:func:`apply_ufunc` (:pull:`5041`)
- :py:meth:`Dataset.interp` now allows interpolation with non-numerical datatypes,
such as booleans, instead of dropping them. (:issue:`4761` :pull:`5008`).
- Raise more informative error when decoding time variables with invalid reference dates.
(:issue:`5199`, :pull:`5288`).
Bug fixes
- Opening netCDF files from a path that doesn't end in ``.nc`` without supplying
an explicit ``engine`` works again (:issue:`5295`), fixing a bug introduced in
0.18.0.
Documentation
- Clean up and enhance docstrings for the :py:class:`DataArray.plot` and ``Dataset.plot.*``
families of methods (:pull:`5285`).
- Explanation of deprecation cycles and how to implement them added to contributors
guide. (:pull:`5289`)

the package previously used PKG_OPTIONS for this, but PKG_OPTIONS
are harmful in the case that they effect the resulting ABI of
library packages. this way, things that actually need fftwl and fftwq
can depend on these sub-packages.
this also fixes fftwq on NetBSD by making it pull in libquadmath.
another thing about PKG_OPTIONS for library components is that
they mean certain components don't get tested...
This was lost on the recent rework of the patches:
On NetBSD.
In PKGSRC_FORTRAM=gfortran case, libcblas has no RPATH=/usr/pkg/gccXX/lib
and libgfortran and libquadmath are not found.
In PKGSRC_FORTRAN=g95 case, libcblas has no
RPATH=/usr/pkg/lib/gcc-lib/x86_64--netbsd/4.1.2 and libf95 is not found.
Use Fortran compiler as linker instread of C compiler to fix link.
