API changes, several new features, enhancements, and performance
improvements along with a large number of bug fixes. We recommend that
all users upgrade to this version.
Highlights include:
DataFrame.assign method

see here
v0.15.0 (October 18, 2014)
This is a major release from 0.14.1 and includes a small number of
API changes, several new features, enhancements, and performance
improvements along with a large number of bug fixes. We recommend that
all users upgrade to this version.
Warning
pandas >= 0.15.0 will no longer support compatibility with NumPy
versions < 1.7.0. If you want to use the latest versions of pandas,
please upgrade to NumPy >= 1.7.0 (GH7711)
Highlights include:
The Categorical type was integrated as a first-class pandas type
New scalar type Timedelta, and a new index type TimedeltaIndex
New datetimelike properties accessor .dt for Series, see
Datetimelike Properties
New DataFrame default display for df.info() to include memory
usage, see Memory Usage
read_csv will now by default ignore blank lines when parsing
API change in using Indexes in set operations
Enhancements in the handling of timezones
A lot of improvements to the rolling and expanding moment funtions
Internal refactoring of the Index class to no longer sub-class
ndarray, see Internal Refactoring
dropping support for PyTables less than version 3.0.0, and
numexpr less than version 2.1 (GH7990)
Split indexing documentation into Indexing and Selecting Data
and MultiIndex / Advanced Indexing
Split out string methods documentation into Working with Text Data
{perl>=5.16.6,p5-ExtUtils-ParseXS>=3.15}:../../devel/p5-ExtUtils-ParseXS
since pkgsrc enforces the newest perl version anyway, so they
should always pick perl, but sometimes (pkg_add) don't due to the
design of the {,} syntax.
No effective change for the above reason.

Upstream changes:
CHANGES IN R 3.2.1
NEW FEATURES
utf8ToInt() now checks that its input is valid UTF-8 and returns NA if it is not.
install.packages() now allows type = "both" with repos = NULL if it can infer the type of file.
nchar(x, *) and nzchar(x) gain a new argument keepNA which governs how the result for NAs in x is determined. For the R 3.2.x series, the default remains FALSE which is fully back compatible. From R 3.3.0, the default will change to keepNA = NA and you are advised to consider this for code portability.
news() more flexibly extracts dates from package ‘NEWS.Rd’ files.
lengths(x) now also works (trivially) for atomic x and hence can be used more generally as an efficient replacement of sapply(x, length) and similar.
The included version of PCRE has been updated to 8.37, a bug-fix release.
diag() no longer duplicates a matrix when extracting its diagonal.
as.character.srcref() gains an argument to allow characters corresponding to a range of source references to be extracted.
BUG FIXES
acf() and ccf() now guarantee values strictly in [-1,1] (instead of sometimes very slightly outside). PR#15832.
as.integer("111111111111") now gives NA (with a warning) as it does for the corresponding numeric or negative number coercions. Further, as.integer(M + 0.1) now gives M (instead of NA) when M is the maximal representable integer.
On some platforms nchar(x, "c") and nchar(x, "w") would return values (possibly NA) for inputs which were declared to be UTF-8 but were not, or for invalid strings without a marked encoding in a multi-byte locale, rather than give an error. Additional checks have been added to mitigate this.
apply(a, M, function(u) c(X = ., Y = .)) again has dimnames containing "X" and "Y" (as in R < 3.2.0).
(Windows only) In some cases, the --clean option to R CMD INSTALL could fail. (PR#16178)
(Windows only) choose.files() would occasionally include characters from the result of an earlier call in the result of a later one. (PR#16270)
A change in RSiteSearch() in R 3.2.0 caused it to submit invalid URLs. (PR#16329)
Rscript and command line R silently ignored incomplete statements at the end of a script; now they are reported as parse errors. (PR#16350)
Parse data for very long strings was not stored. (PR#16354)
plotNode(), the workhorse of the plot method for "dendrogram"s is no longer recursive, thanks to Suharto Anggono, and hence also works for deeply nested dendrograms. (PR#15215)
The parser could overflow internally when given numbers in scientific format with extremely large exponents. (PR#16358)
If the CRAN mirror was not set, install.packages(type = "both") and related functions could repeatedly query the user for it. (Part of PR#16362)
The low-level functions .rowSums() etc. did not check the length of their argument, so could segfault. (PR#16367)
The quietly argument of library() is now correctly propagated from .getRequiredPackages2().
Under some circumstances using the internal PCRE when building R fron source would cause external libs such as -llzma to be omitted from the main link.
The .Primitive default methods of the logic operators, i.e., !, & and |, now give correct error messages when appropriate, e.g., for `&`(TRUE) or `!`(). (PR#16385)
cummax(x) now correctly propagates NAs also when x is of type integer and begins with an NA.
summaryRprof() could fail when the profile contained only two records. (PR#16395)
HTML vignettes opened using vignette() did not support links into the rest of the HTML help system. (Links worked properly when the vignette was opened using browseVignettes() or from within the help system.)
arima(*, xreg = .) (for d >= 1) computes estimated variances based on a the number of effective observations as in R version 3.0.1 and earlier. (PR#16278)
slotNames(.) is now correct for "signature" objects (mostly used internally in methods).
On some systems, the first string comparison after a locale change would result in NA.
Upstream changes:
Version 1.0
2015-02-10 Convert rngs to real function in accordance with pan
Cast rangen explicitly as real
Revise DESCRIPTION and remove .Rinstignore
Upstream changes:
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
o switch to standard NEWS format
Upstream changes:
Changes in 4.6-10:
* Fixed bugs introduced in 4.6-8 and 4.6-9. Levels for ordered factors
in predictors are no longer checked for consistency between training
and test data in predict.randomForest(). In 4.6-9 the response is mean
centered before running the algorithm (for regression), but the mean was
not added back in the $y component of the return object from
randomForest().
Changes in 4.6-9:
* Categorical predictors are allowed to have up to 53 categories now.
Changes in 4.6-8:
* There was a bug in the handling of ordered factors in randomForest.formula().
(Reported by Barry Rawlingson.)
* Changed randomForest.formula() and predict.randomForest() so that
predict() without newdata when na.action=na.exclude pads the output
with NAs to match the rows in the original data (suggested by Barry
Rawlingson.).
* There was a long standing bug in randomForest(..., proximity=TRUE, oob.prox=FALSE)
in regression mode. (Thanks to Stefano Romano for the report.)
Upstream changes:
30 March 2015: statmod 1.4.21
- qinvgauss() now treats input arguments of different lengths or NA
parameter values more carefully.
- elda() now gracefully removes structural zeros, i.e., rows where
the number of cells or the number of assays is zero.
- S3 print and plot methods for "limdil" class now registered.
- Use of require("tweedie") in the qres.tweedie() code replaced by
requireNameSpace("tweedie").
Upstream changes:
Changes in Version 1.7-12
o read.zoo with a data.frame argument now defaults to FUN = identity
if the index.column is not character or factor. See ?read.zoo for
additional details.
o Added a dim<- method that checks whether the new dimension value
appears to be ok and then calls the default.
o The index<- and time<- methods now enforce that the new time index
is actually correctly ordered (suggested by Joshua Ulrich).
o read.zoo() heuristic improved so that POSIXct rather than Date is
detected in cases like: read.zoo(text = "2010-01-01 12:05:03 88.1",
index = 1:2).
o The fortify() method now has a col.names argument that allows to set
(some of) the column names of the resulting data.frame.
o Various small bug fixes and enhancements.
Changelog:
CHANGES IN 3.2.0:
NEW FEATURES:
* anyNA() gains a recursive argument.
* When x is missing and names is not false (including the default
value), Sys.getenv(x, names) returns an object of class "Dlist"
and hence prints tidily.
* (Windows.) shell() no longer consults the environment variable
SHELL: too many systems have been encountered where it was set
incorrectly (usually to a path where software was compiled, not
where it was installed). R_SHELL, the preferred way to select a
non-default shell, can be used instead.
* Some unusual arguments to embedFonts() can now be specified as
character vectors, and the defaults have been changed
accordingly.
* Functions in the Summary group duplicate less. (PR#15798)
* (Unix-alikes.) system(cmd, input = ) now uses
'shell-execution-environment' redirection, which will be more
natural if cmd is not a single command (but requires a
POSIX-compliant shell). (Wish of PR#15508)
* read.fwf() and read.DIF() gain a fileEncoding argument, for
convenience.
* Graphics devices can add attributes to their description in
.Device and .Devices. Several of those included with R use a
"filepath" attribute.
* pmatch() uses hashing in more cases and so is faster at the
expense of using more memory. (PR#15697)
* pairs() gains new arguments to select sets of variables to be
plotted against each other.
* file.info(, extra_cols = FALSE) allows a minimal set of columns
to be computed on Unix-alikes: on some systems without
properly-configured caching this can be significantly faster with
large file lists.
* New function dir.exists() in package base to test efficiently
whether one or more paths exist and are directories.
* dput() and friends gain new controls hexNumeric and digits17
which output double and complex quantities as, respectively,
binary fractions (exactly, see sprintf("%a")) and as decimals
with up to 17 significant digits.
* save(), saveRDS() and serialize() now support ascii = NA which
writes ASCII files using sprintf("%a") for double/complex
quantities. This is read-compatible with ascii = TRUE but avoids
binary->decimal->binary conversions with potential loss of
precision. Unfortunately the Windows C runtime's lack of C99
compliance means that the format cannot be read correctly there
in R before 3.1.2.
* The default for formatC(decimal.mark =) has been changed to be
getOption("OutDec"); this makes it more consistent with format()
and suitable for use in print methods, e.g. those for classes
"density", "ecdf", "stepfun" and "summary.lm".
getOption("OutDec") is now consulted by the print method for
class "kmeans", by cut(), dendrogram(), plot.ts() and quantile()
when constructing labels and for the report from legend(trace =
TRUE).
(In part, wish of PR#15819.)
* printNum() and hence format() and formatC() give a warning if
big.mark and decimal.mark are set to the same value (period and
comma are not uncommonly used for each, and this is a check that
conventions have not got mixed).
* merge() can create a result which uses long vectors on 64-bit
platforms.
* dget() gains a new argument keep.source which defaults to FALSE
for speed (dput() and dget() are most often used for data objects
where this can make dget() many times faster).
* Packages may now use a file of common macro definitions in their
help files, and may import definitions from other packages.
* A number of macros have been added in the new share/Rd directory
for use in package overview help pages, and promptPackage() now
makes use of them.
* tools::parse_Rd() gains a new permissive argument which converts
unrecognized macros into text. This is used by
utils:::format.bibentry to allow LaTeX markup to be ignored.
* options(OutDec =) can now specify a multi-byte character, e.g.,
options(OutDec = "\u00b7") in a UTF-8 locale.
* is.recursive(x) is no longer true when x is an external pointer,
a weak reference or byte code; the first enables all.equal(x, x)
when x <- getClass(.).
* ls() (aka objects()) and as.list.environment() gain a new
argument sorted.
* The "source" attribute (which has not been added to functions by
R since before R version 2.14.0) is no longer treated as special.
* Function returnValue() has been added to give on.exit() code
access to a function's return value for debugging purposes.
* crossprod(x, y) allows more matrix coercions when x or y are
vectors, now equalling t(x) %*% y in these cases (also reported
by Radford Neal). Similarly, tcrossprod(x,y) and %*% work in
more cases with vector arguments.
* Utility function dynGet() useful for detecting cycles, aka
infinite recursions.
* The byte-code compiler and interpreter include new instructions
that allow many scalar subsetting and assignment and scalar
arithmetic operations to be handled more efficiently. This can
result in significant performance improvements in scalar
numerical code.
* apply(m, 2, identity) is now the same as the matrix m when it has
_named_ row names.
* A new function debuggingState() has been added, allowing to
temporarily turn off debugging.
* example() gets a new optional argument run.donttest and
tools::Rd2ex() a corresponding commentDonttest, with a default
such that example(..) in help examples will run \donttest code
only if used interactively (a change in behaviour).
* rbind.data.frame() gains an optional argument make.row.names, for
potential speedup.
* New function extSoftVersion() to report on the versions of
third-party software in use in this session. Currently reports
versions of zlib, bzlib, the liblzma from xz, PCRE, ICU, TRE and
the iconv implementation.
A similar function grSoftVersion() in package grDevices reports
on third-party graphics software.
Function tcltk::tclVersion() reports the Tcl/Tk version.
* Calling callGeneric() without arguments now works with primitive
generics to some extent.
* vapply(x, FUN, FUN.VALUE) is more efficient notably for large
length(FUN.VALUE); as extension of PR#16061.
* as.table() now allows tables with one or more dimensions of
length 0 (such as as.table(integer())).
* names(x) <- NULL now clears the names of call and ... objects.
* library() will report a warning when an insufficient dependency
version is masking a sufficient one later on the library search
path.
* A new plot() method for class "raster" has been added.
* New check_packages_in_dir_changes() function in package tools for
conveniently analyzing how changing sources impacts the check
results of their reverse dependencies.
* Speed-up from Peter Haverty for ls() and
methods:::.requirePackage() speeding up package loading.
(PR#16133)
* New get0() function, combining exists() and get() in one call,
for efficiency.
* match.call() gains an envir argument for specifying the
environment from which to retrieve the ... in the call, if any;
this environment was wrong (or at least undesirable) when the
definition argument was a function.
* topenv() has been made .Internal() for speedup, based on Peter
Haverty's proposal in PR#16140.
* getOption() no longer calls options() in the main case.
* Optional use of libcurl (version 7.28.0 from Oct 2012 or later)
for Internet access:
* capabilities("libcurl") reports if this is available.
* libcurlVersion() reports the version in use, and other
details of the "libcurl" build including which URL schemes it
supports.
* curlGetHeaders() retrieves the headers for http://, https://,
ftp:// and ftps:// URLs: analysis of these headers can
provide insights into the `existence' of a URL (it might for
example be permanently redirected) and is so used in R CMD
check --as-cran.
* download.file() has a new optional method "libcurl" which
will handle more URL schemes, follow redirections, and allows
simultaneous downloads of multiple URLs.
* url() has a new method "libcurl" which handles more URL
schemes and follows redirections. The default method is
controlled by a new option url.method, which applies also to
the opening of URLs _via_ file() (which happens implicitly in
functions such as read.table.)
* When file() or url() is invoked with a https:// or ftps://
URL which the current method cannot handle, it switches to a
suitable method if one is available.
* (Windows.) The DLLs internet.dll and internet2.dll have been
merged. In this version it is safe to switch (repeatedly)
between the internal and Windows internet functions within an R
session.
The Windows internet functions are still selected by flag
--internet2 or setInternet2(). This can be overridden for an
url() connection _via_ its new method argument.
download.file() has new method "wininet", selected as the default
by --internet2 or setInternet2().
* parent.env<- can no longer modify the parent of a locked
namespace or namespace imports environment. Contributed by Karl
Millar.
* New function isLoadedNamespace() for readability and speed.
* names(env) now returns all the object names of an environment
env, equivalently to ls(env, all.names = TRUE, sorted = FALSE)
and also to the names of the corresponding list,
names(as.list(env, all.names = TRUE)). Note that although
names() returns a character vector, the names have no particular
ordering.
* The memory manager now grows the heap more aggressively. This
reduces the number of garbage collections, in particular while
data or code are loaded, at the expense of slightly increasing
the memory footprint.
* New function trimws() for removing leading/trailing whitespace.
* cbind() and rbind() now consider S4 inheritance during S3
dispatch and also obey deparse.level.
* cbind() and rbind() will delegate recursively to methods::cbind2
(methods::rbind2) when at least one argument is an S4 object and
S3 dispatch fails (due to ambiguity).
* (Windows.) download.file(quiet = FALSE) now uses text rather
than Windows progress bars in non-interactive use.
* New function hsearch_db() in package utils for building and
retrieving the help search database used by help.search(), along
with functions for inspecting the concepts and keywords in the
help search database.
* New function .getNamespaceInfo(), a no-check version of
getNamespaceInfo() mostly for internal speedups.
* The help search system now takes \keyword entries in Rd files
which are not standard keywords (as given in KEYWORDS in the R
documentation directory) as concepts. For standard keyword
entries the corresponding descriptions are additionally taken as
concepts.
* New lengths() function for getting the lengths of all elements in
a list.
* New function toTitleCase() in package tools, tailored to package
titles.
* The matrix methods of cbind() and rbind() allow matrices as
inputs which have 2^31 or more elements. (For cbind(), wish of
PR#16198.)
* The default method of image() has an explicit check for a numeric
or logical matrix (which was always required).
* URLencode() will not by default encode further URLs which appear
to be already encoded.
* BIC(mod) and BIC(mod, mod2) now give non-NA numbers for arima()
fitted models, as nobs(mod) now gives the number of "used"
observations for such models. This fixes PR#16198, quite
differently than proposed there.
* The print() methods for "htest", "pairwise.htest" and
"power.htest" objects now have a digits argument defaulting to (a
function of) getOption("digits"), and influencing all printed
numbers coherently. Unavoidably, this changes the display of
such test results in some cases.
* Code completion for namespaces now recognizes all loaded
namespaces, rather than only the ones that are also attached.
* The code completion mechanism can now be replaced by a
user-specified completer function, for (temporary) situations
where the usual code completion is inappropriate.
* unzip() will now warn if it is able to detect truncation when
unpacking a file of 4GB or more (related to PR#16243).
* methods() reports S4 in addition to S3 methods; output is
simplified when the class argument is used. .S3methods() and
methods::.S4methods() report S3 and S4 methods separately.
* Higher order functions such as the apply functions and Reduce()
now force arguments to the functions they apply in order to
eliminate undesirable interactions between lazy evaluation and
variable capture in closures. This resolves PR#16093.
INSTALLATION and INCLUDED SOFTWARE:
* The \donttest sections of R's help files can be tested by
make check TEST_DONTTEST=TRUE .
* It is possible to request the use of system valgrind headers
_via_ configure option --with-system-valgrind-headers: note the
possible future incompatibility of such headers discussed in the
'R Installation and Administration' manual. (Wish of PR#16068.)
* The included version of liblzma has been updated to xz-utils
5.0.7 (minor bug fixes from 5.0.5).
* configure options --with-system-zlib, --with-system-bzlib and
--with-system-pcre are now the default. For the time being there
is fallback to the versions included in the R sources if no
system versions are found or (unlikely) if they are too old.
Linux users should check that the -devel or -dev versions of
packages zlib, bzip2/libbz2 and pcre as well as
xz-devel/liblzma-dev (or similar names) are installed.
* configure by default looks for the texi2any script from texinfo
5.1 or later, rather than the makeinfo program. (makeinfo is a
link to the Perl script texi2any in texinfo 5.x.)
* R CMD INSTALL gains an option --built-timestamp=STAMP allowing
100% reproducible package building, thanks to Dirk Eddelbuettel.
UTILITIES:
* There is support for testing the \dontrun and \donttest parts of
examples in packages.
tools::testInstalledPackage() accepts new arguments
commentDontrun = FALSE and commentDonttest = FALSE.
R CMD check gains options --run-dontrun and --run-donttest.
* The HTML generated by tools::Rd2HTML() and tools::toHTML()
methods is now 'XHTML 1.0 Strict'.
* The compiler package's utility function setCompilerOptions() now
returns the old values invisibly. The initial optimization level
can also be set with the environment variable
R_COMPILER_OPTIMIZE.
* R CMD build adds a NeedsCompilation field if one is not already
present in the DESCRIPTION file.
* R CMD check gains option --test-dir to specify an alternative set
of tests to run.
* R CMD check will now by default continue with testing after many
types of errors, and will output a summary count of errors at the
end if any have occurred.
* R CMD check now checks that the Title and Description fields are
correctly terminated.
* R CMD check --as-cran now:
* checks a README.md file can be processed: this needs pandoc
installed.
* checks the existence and accessibility of URLs in the
DESCRIPTION, CITATION, NEWS.Rd and README.md files and in the
help files (provided the build has libcurl support).
* reports non-ASCII characters in R source files when there is
no package encoding declared in the DESCRIPTION file.
* reports (apparent) S3 methods exported but not registered.
* reports overwriting registered S3 methods from
base/recommended packages. (Such methods are replaced in the
affected package for the rest of the session, even if the
replacing namespace is unloaded.)
* reports if the Title field does not appear to be in title
case (see 'Writing R Extensions': there may be false
positives, but note that technical words should be
single-quoted and will then be accepted).
Most of these checks can also be selected by environment
variables: see the 'R Internals' manual.
C-LEVEL FACILITIES:
* New C API utility logspace_sum(logx[], n).
* Entry points rbinom_mu, rnbinom_mu and rmultinom are remapped (by
default) to Rf_rbinom_mu etc. This requires packages using them
to be re-installed.
* .C(DUP = FALSE) and .Fortran(DUP = FALSE) are now ignored, so
arguments are duplicated if DUP = TRUE would do so. As their
help has long said, .Call() is much preferred.
* New entry point R_allocLD, like R_alloc but guaranteed to have
sufficient alignment for long double pointers.
* isPairList() now returns TRUE for DOTSXP.
WINDOWS BUILD CHANGES:
A number of changes to the Windows build system are in development.
The following are currently in place.
* Installation using external binary distributions of zlib, bzip2,
liblzma, pcre, libpng, jpeglib and libtiff is now required, and
the build instructions have been revised.
* A new make target rsync-extsoft has been added to obtain copies
of the external libraries from CRAN.
* Building the manuals now requires texi2any from texinfo 5.1 or
later. CRAN binary builds include the manuals, but by default
builds from source will not, and they will be accessed from CRAN.
See the comments in src/gnuwin32/MkRules.dist for how to specify
the location of texi2any.
* (Windows) Changes have been made to support an experimental
Windows toolchain based on GCC 4.9.2. The default toolchain
continues to be based on GCC 4.6.3, as the new toolchain is not
yet stable enough. A change to a new toolchain is expected
during the R 3.2.x lifetime.
PACKAGE INSTALLATION:
* (Windows) The use of macro ZLIB_LIBS in file src/Makevars.win
(which has not been documented for a long time) now requires an
external libz.a to be available (it is part of the 'goodies' used
to compile Windows binary packages). It would be simpler to use
-lz instead.
* The default for option pkgType on platforms using binary packages
is now "both", so source packages will be tried if binary
versions are not available or not up to date.
There are options for what install.packages(type = "both")
(possibly called _via_ update.packages()) will do if compilation
of a source package is desirable: see ?options (under utils).
If you intend not to accept updates as source packages, you
should use update.packages(type = "binary").
DEPRECATED AND DEFUNCT:
* download.file(method = "lynx") is defunct.
* Building R using the included versions of zlib, bzip2, xz and
PCRE is deprecated: these are frozen (bar essential bug-fixes)
and will be removed for R 3.3.0.
* The configure option --with-valgrind-instrumentation=3 has been
withdrawn, as it did not work with recent valgrind headers: it is
now treated as level 2.
* The MethodsList class in package methods had been deprecated in R
2.11.0 and is defunct now. Functions using it are defunct if
they had been deprecated in R 2.11.0, and are deprecated now,
otherwise.
BUG FIXES:
* Fixed two obscure bugs in pairlist subassignment, reported by
Radford Neal as part of pqR issue 16.
* Fixes for bugs in handling empty arguments and argument matching
by name in log().
* all.equal() gains methods for environments and refClasses.
* [<- and [[<- gain S4 data.frame methods to avoid corruption of S4
class information by the S3 methods.
* callNextMethod() should now work within a .local call when ... is
absent from formals(.local).
* dput(pairlist(x)) generates a call to the pairlist constructor
instead of the list constructor.
* Fix missing() when arguments are propagated through ... .
(PR#15707)
* eigen(m) now defaults to symmetric = TRUE even when the dimnames
are asymmetric if the matrix is otherwise symmetric. (PR#16151)
* Fix issues with forwarding ... through callGeneric() and
callNextMethod(). (PR#16141)
* callGeneric() now works after a callNextMethod().
* Subclass information is kept consistent when replacing an
ordinary S4 class with an "old class" _via_ the S4Class argument
to setOldClass(). Thus, for example, a data.frame is valid for a
list argument in the signature, and a factor is valid for vector
arguments.
* In qbeta() the inversion of pbeta() is much more sophisticated.
This works better in corner cases some of which failed completely
previously (PR#15755), or were using too many iterations.
* Auto-printing no longer duplicates objects when printing is
dispatched to a method.
* kmeans(x, k) would fail when nrow(x) >= 42949673. (Comment 6 of
PR#15364)
* 'Abbreviated' locale-specific day and month names could have been
truncated in those rare locales where there are the same as the
full names.
* An irrelevant warning message from updating subclass information
was silenced (the namespace would not be writable in this case).
CHANGES IN R 3.1.3:
NEW FEATURES:
* The internal method of download.file() can now handle files
larger than 2GB on 32-bit builds which support such files (tested
on 32-bit R running on 64-bit Windows).
* kruskal.test() warns on more types of suspicious input.
* The as.dendrogram() method for "hclust" objects gains a check
argument protecting against memory explosion for invalid inputs.
* capabilities() has a new item long.double which indicates if the
build uses a long double type which is longer than double.
* nlm() no longer modifies the callback argument in place (a new
vector is allocated for each invocation, which mimics the
implicit duplication that occurred in R < 3.1.0); note that this
is a change from the previously documented behavior. (PR#15958)
* icuSetCollate() now accepts locale = "ASCII" which uses the basic
C function strcmp and so collates strings byte-by-byte in
numerical order.
* sessionInfo() tries to report the OS version in use (not just
that compiled under, and including details of Linux
distributions).
* model.frame() (used by lm() and many other modelling functions)
now warns when it drops contrasts from factors. (Wish of
PR#16119)
* install.packages() and friends now accept the value type =
"binary" as a synonym for the native binary type on the platform
(if it has one).
* Single source or binary files can be supplied for
install.packages(type = "both") and the appropriate type and
repos = NULL will be inferred.
* New function pcre_config() to report on some of the configuration
options of the version of PCRE in use. In particular, this
reports if regular expressions using \p{xx} are supported.
* (Windows.) download.file(cacheOK = FALSE) is now supported when
internet2.dll is used.
* browseURL() has been updated to work with Firefox 36.0 which has
dropped support for the -remote interface.
INSTALLATION and INCLUDED SOFTWARE:
* The included version of PCRE has been updated to 8.36.
* configure accepts MAKEINFO=texi2any as another way to ensure
texinfo 5.x is used when both 5.x and 4.x are installed.
UTILITIES:
* R CMD check now checks the packages used in \donttest sections of
the examples are specified in the DESCRIPTION file. (These are
needed to run the examples interactively.)
* R CMD check checks for the undeclared use of GNU extensions in
Makefiles, and for Makefiles with a missing final linefeed.
R CMD build will correct line endings in all Makefiles, not just
those in the src directory.
* R CMD check notes uses of library() and require() in package
code: see the section 'Suggested packages' of 'Writing R
Extensions' for good practice.
DEPRECATED AND DEFUNCT:
* The configure option --with-valgrind-instrumentation=3 is
deprecated and will be removed in R 3.2.0.
BUG FIXES:
* (Windows.) Rscript.exe was missing a manifest specifying the
modern style for common controls (e.g., the download progress
bar).
* If a package had extra documentation files but no vignette, the
HTML help system produced an empty index page.
* The parser now gives an error if a null character is included in
a string using Unicode escapes. (PR#16046)
* qr.Q() failed on complex arguments due to pre-3.0(!) typo.
(PR#16054)
* abs() failed with named arguments when the argument was complex.
(PR#16047)
* "noquote" objects may now be used as columns in dataframes.
(PR#15997)
* Some values with extremely long names were printed incorrectly.
(PR#15999)
* Extremely large exponents on zero expressed in scientific
notation (e.g. 0.0e50000) could give NaN. (PR#15976)
* download.file() reported downloaded sizes as 0KB if less than
1MB, only for R 3.1.2 and only on big-endian platforms.
* prompt() did not escape percent signs in the automatically
generated usage section of help files.
* drop.terms() dropped some of the attributes of the object it was
working with. (PR#16029)
* (Windows.) The command completion in Rgui.exe messed up the
console. (PR#15791)
* (Windows.) The choose.files() command returned a blank string
when the user asked for a single file but cancelled the request.
(PR#16074)
* Math2 S4 group generics failed to correctly dispatch "structure"-
and "nonStructure"-derived classes.
* loadNamespace() imposed undocumented restrictions on the
versionCheck parameter. (Reported by Geoff Lee.)
* Rare over-runs detected by AddressSanitizer in substr() and its
replacement version have been avoided.
_Inter alia_ that fix gives the documented behaviour for
substr(x, 1, 2) <- "" (subsequently reported as PR#16214).
* Loading packages incorrectly defining an S4 generic followed by a
function of the same name caused an erroneous cyclic namespace
dependency error.
* Declared vignette encodings are now always passed to the vignette
engine.
* Port Tomas Kalibera's fix from R-devel that restores the
loadMethod() fast path, effectively doubling the speed of S4
dispatch.
* power.t.test() and power.prop.test() now make use of the
extendInt option of uniroot() and hence work in more extreme
cases. (PR#15792)
* If a package was updated and attached when its namespace was
already loaded, it could end up with parts from one version and
parts from the other. (PR#16120)
* tools:::.Rdconv() didn't accept --encoding= due to a typo.
(PR#16121)
* Unix-alike builds without a suitable makeinfo were documented to
link the missing HTML manuals to CRAN, but did not.
* save(*, ascii=TRUE) and load() now correctly deal with NaN's.
(PR#16137)
* split.Date() retains fractional representations while avoiding
incomplete class propagation.
* R_ext/Lapack.h had not been updated for changes made by LAPACK to
the argument lists of its (largely internal) functions dlaed2 and
dlaed3. (PR#16157)
* RShowDoc("NEWS", "txt") had not been updated for the layout
changes of R 3.1.0.
* The xtfrm() method for class "Surv" has been corrected and its
description expanded.
* mode(x) <- y would incorrectly evaluate x before changing its
mode. (PR#16215)
* besselJ(1, 2^64) and besselY(..) now signal a warning, returning
NaN instead of typically segfaulting. (Issue 3 of PR#15554)
* HTML conversion of \href markup in .Rd files did not remove the
backslash from \% and so gave an invalid URL. In a related
change, the \ escape is now required in such URLs.
CHANGES IN R 3.1.2:
NEW FEATURES:
* embedFonts() now defaults to format = "ps2write" for .ps and .eps
files. This is available in Ghostscript 9.x (since 2010) whereas
the previous default, format = "pswrite", was removed in
Ghostscript 9.10.
* For consistency with [dpqr]norm(), [dp]lnorm(sdlog = 0) model a
point mass at exp(mulog) rather than return NaN (for an error).
* capabilities() now reports if ICU is compiled in for use for
collation (it is only actually used if a suitable locale is set
for collation, and never for a C locale).
* (OS X only.) Package tcltk checks when loaded if it is linked
against the CRAN X11-based Tcl/Tk and if so that the Tcl/Tk
component and the X11 libraries are installed. This allows more
informative error messages to be given advising the installation
of the missing component or of XQuartz.
The X11() device and X11-based versions of the data editor and
viewer (invoked by edit() and View() for data frames and matrices
from command-line R) check that the X11 libraries are installed
and if not advises installing XQuartz.
* icuSetCollate() allows locale = "default", and locale = "none" to
use OS services rather than ICU for collation.
Environment variable R_ICU_LOCALE can be used to set the default
ICU locale, in case the one derived from the OS locale is
inappropriate (this is currently necessary on Windows).
* New function icuGetCollate() to report on the ICU collation
locale in use (if any).
* utils::URLencode() was updated to use unreserved and reserved
characters from RFC 3986 (<URL:
http://tools.ietf.org/html/rfc3986>) instead of RFC 1738.
* unique(warnings()) and c(warnings()) are now supported.
* The Bioconductor 'version' used by setRepositories() now defaults
to 3.0. (It can be set at runtime _via_ environment variable
R_BIOC_VERSION.)
* Omegahat is no longer listed as providing Windows binary
packages, e.g. by setRepositories(). It has no binary packages
available for R 3.1.x and those for earlier versions were 32-bit
only.
INSTALLATION and INCLUDED SOFTWARE:
* The configure script reports on the more important
capabilities/options which will not be compiled in.
More types of external BLAS are recognized by name in that
report.
* When building R as a shared library, the -L${R_HOME}/lib${R_ARCH}
flag is placed earlier in the link commands used during
installation and when packages are installed: this helps ensure
that the current build has priority if an R shared library has
already been installed by e.g. install-libR in a library
mentioned in LDFLAGS (and not in 'your system's library
directory' as documented). (Wish of PR#15790.)
* LaTeX package upquote is no longer required for R's use of
inconsolata.
* (Windows only) If both 32- and 64-bit versions of R are
installed, the bin/R.exe and bin/Rscript.exe executables now run
64-bit R. (To run 32-bit R, overwrite these files with copies of
bin/i386/Rfe.exe.)
UTILITIES:
* Running R CMD check with _R_CHECK_DEPENDS_ONLY_ true now makes
the VignetteBuilder packages available even if they are listed in
Suggests, since they are needed to recognise and process
non-Sweave vignettes.
* R CMD check now reports empty importFrom declarations in a
NAMESPACE file, as these are common errors (writing
importFrom(Pkg) where import(Pkg) was intended).
* R CMD check now by default checks code usage directly on the
package namespace without loading and attaching the package and
its suggests and enhances. For good practice with packages in
the Suggests field, see SS1.1.3.1 of 'Writing R Extensions'. For
use of lazy-data objects in the package's own code, see ?data.
BUG FIXES:
* dmultinom() did not handle non-finite probabilities correctly.
* prettyNum(x, zero.print=*) now also works when x contains NAs.
* A longstanding bug exhibited by nlminb() on Windows was traced to
a compiler bug in gcc 4.6.3; a workaround has been put in place.
(PR#15244 and PR#15914).
* Rendering of \command in HTML versions of help pages has been
improved: this is particularly evident on the help page for
INSTALL.
* as.hexmode(x) and as.octmode(x) now behave correctly for some
numeric x, e.g., c(NA, 1) or c(1, pi).
* drop1() failed if the scope argument had no variables to drop.
(PR#15935)
* edit() (and hence fix()) failed if an object had a non-character
attribute named "source" (an attribute that had been used in R
prior to version 2.14.0).
* callGeneric() could fail if the generic had ... as a formal
argument. (PR#15937).
* Forking in package parallel called C entry point exit in the
child. This was unsafe (_exit should have been called), and
could flush stdin of the main R process (seen most often on
Solaris).
As good practice, stdout is now flushed before forking a child.
* R objects such as list(`a\b` = 1) now print correctly.
* getAnywhere("C_pbinom") now returns correctly a single object
(rather than unlisting it).
* The confint() method for nls() fits failed it these has specified
parameter limits despite using an algorithm other than "port".
(PR#15960)
* Subclassing an S4 class failed if the class required arguments to
the generator, through its initialize() method.
* removeSource() did not properly handle expressions containing
arguments that were supplied as missing, e.g. x[i,]. (PR#15957)
* as.environment(list()) now works, and as.list() of such an
environment is now the same as list().
* Several tcltk functions failed when run in unusual environments.
(PR#15970)
* options(list()) now works (trivially). (PR#15979)
* merge(<dendrogram>, ..) now works correctly for two `independent'
dendrograms (PR#15648), and still compatibly via adjust = "auto"
e.g. for two branches of an existing dendrogram.
* The plot method for "hclust" objects gets an optional argument
check; When that is true (the default) it checks more carefully
for valid input.
* (Windows only) If a user chose to install 64 bit R but not 32 bit
R, the bin/R and bin/Rscript executables failed to run.
(PR#15981)
* Various possible buffer overruns have been prevented, and missed
memory protection added. (PR#15990)
* Rscript no longer passes --args to R when there are no extra
("user") arguments.
* objects like getClass("refClass")@prototype now print() and str()
without error.
* identical() now also looks at the S4 bit.
* hist(x, breaks) is more robust in adding a small fuzz to few
breaks when some are very large. (PR#15988)
* sub() and gsub() did not handle regular expressions like "\s{2,}"
properly if the text contained NA or non-ascii elements in a
UTF-8 locale. Part of this was due to a bug in the TRE library.
(PR#16009)
* RShowDoc("NEWS") now displays the PDF version.
* Matrices and arrays with last dimension zero did not print at all
or incompletely. (PR#16012)
* plot.histogram() and hence hist() now respect the xaxs, yaxs and
lab graphics parameters. (PR#16021)
* bw.SJ(x) and other bw.*() no longer segfault when x contains
non-finite values. (PR#16024)
* R CMD Rd2pdf unintentionally ignored its --os option.
* The internal method of download.file() was not reporting file
sizes and progress correctly on files larger than 2GB (inherited
from libxml2). This is corrected for 64-bit builds (32-bit
platforms may not support such files, but where possible will be
supported in future versions of R).
* Work around a bug in OS X Yosemite where key environment
variables may be duplicated causing issues in subprocesses. The
duplicates are now removed on R startup (via Rprofile).
(PR#16042)
* Adjust X11 auto-launch detection in DISPLAY on OS X to recognize
latest XQuartz.
