labeling sequential data. The first priority of this software is to
train and use CRF models as fast as possible even at the expense of
its memory space and code generality. CRFsuite runs 5.4 - 61.8 times
faster than C++ implementations for training. CRFsuite supports
parameter estimation with L1 regularization (Laplacian prior) using
Orthant-Wise Limited-memory Quasi-Newton (OW-LQN) method and L2
regularization (Gaussian prior) using Limited-memory BFGS (L-BFGS)
method.
analysis. It can handle the classification of, for example, titles,
questions, sentences, and short messages. Main features of
LibShortText include
* It is more efficient than general text-mining packages. On a
typical computer, processing and training 10 million short texts
takes only around half an hour.
* The fast training and testing is built upon the linear classifier
* LIBLINEAR
* Default options often work well without tedious tuning.
* An interactive tool for error analysis is included. Based on the
property that each short text contains few words, LibShortText
provides details in predicting each text.
LIBLINEAR is a linear classifier for data with millions of instances
and features. It supports
L2-regularized classifiers
L2-loss linear SVM, L1-loss linear SVM, and logistic regression (LR)
L1-regularized classifiers (after version 1.4)
L2-loss linear SVM and logistic regression (LR)
L2-regularized support vector regression (after version 1.9)
L2-loss linear SVR and L1-loss linear SVR.
Main features of LIBLINEAR include
Same data format as LIBSVM, our general-purpose SVM solver,
and also similar usage
Multi-class classification: 1) one-vs-the rest, 2) Crammer & Singer
Cross validation for model selection
Probability estimates (logistic regression only)
Weights for unbalanced data

Changes compared to math/wxMaxima:
14.09.0:
Bugfixes and compatibility with wxGTK-3.x.
We are happy to announce PyTables 3.1.1.
This is a bug-fix release that addresses a critical bug that make PyTables
unusable on some platforms.
What's new
==========
- Fixed a critical bug that caused an exception at import time.
The error was triggered when a bug in long-double detection is detected
in the HDF5 library (see :issue:`275`) and numpy_ does not expose
`float96` or `float128`. Closes :issue:`344`.
- The internal Blosc_ library has been updated to version 1.3.5.
This fixes a false buffer overrun condition that made c-blosc to fail,
even if the problem was not real.
As always, a large amount of bugs have been addressed and squashed as well.

This package provides a general-purpose tool for dynamic report
generation in R, which can be used to deal with any type of (plain
text) files, including Sweave, HTML, Markdown, reStructuredText,
AsciiDoc, and Textile. R code is evaluated as if it were copied and
pasted in an R terminal thanks to the evaluate package (e.g., we do
not need to explicitly print() plots from ggplot2 or lattice). The
language in code chunks is not restricted to R (there is simple
support to Python and shell scripts, etc). Many features are borrowed
from or inspired by Sweave, cacheSweave, pgfSweave, brew and decumar.
The digest package provides a function 'digest()' for the creation of
hash digests of arbitrary R objects (using the md5, sha-1, sha-256 and
crc32 algorithms) permitting easy comparison of R language objects, as
well as a function 'hmac()' to create hash-based message
authentication code.
Markdown is a plain-text formatting syntax that can be converted to
XHTML or other formats. This package provides R bindings to the
Sundown markdown rendering library.
This package provides syntax highlighting for R source code. Currently
it supports LaTeX and HTML output. Source code of other languages can
be supported via Andre Simon's Highlight package.
This package provides a function tidy_source() to format R source
code. Spaces and indent will be added to the code automatically, and
comments will be preserved under certain conditions, so that R code
will be more human-readable and tidy. There is also a Shiny app as a
user interface in this package (see tidy_app()).
stringr is a set of simple wrappers that make R's string functions
more consistent, simpler and easier to use. It does this by ensuring
that: function and argument names (and positions) are consistent, all
functions deal with NA's and zero length character appropriately, and
the output data structures from each function matches the input data
structures of other functions.
packaged for wip by pho.
In mathematics, a semigroup is an algebraic structure consisting of a set
together with an associative binary operation. A semigroup generalizes a
monoid in that there might not exist an identity element. It also
(originally) generalized a group (a monoid with all inverses) to a type
where every element did not have to have an inverse, thus the name
semigroup.
Some internal (non-API) routines to estimate the condition of
the basis matrix were added. These routines are mainly intended
to be used by the simplex-based solvers.
Two open modes "a" and "ab" were added to GLPK I/O routines.
Minor bug was fixed in the solver glpsol (command-line options
--btf, --cbg, and --cgr didn't work properly).
A serious bug was fixed in a basis factorization routine used
on the dense phase. (The bug might appear only if the number of
rows exceeded sqrt(2**31) ~= 46,340 and caused access violation
exception because of integer overflow.)
Two API routines glp_alloc and glp_realloc were documented.
Translation of the document "Modeling Language GNU MathProg"
to Spanish was included (in LaTeX and pdf formats).

This package contains code for generating high quality random numbers that
follow either a uniform or normal distribution. The generated numbers are
suitable for use in statistical applications.
The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222)
multiply-with-carry generator, which has a period of 2^8222 and fares well
in tests of randomness. It is also extremely fast, between 2 and 3 times
faster than the Mersenne Twister.
Compared to the mersenne-random package, this package has a more convenient
API, is faster, and supports more statistical distributions.

Support for Python 3.1 is dropped in this release.
Highlights
Completely rewritten maximum flow and flow-based connectivity algorithms with backwards incompatible interfaces
Community graph generators
Stoer-Wagner minimum cut algorithm

NEW FEATURES:
* When attach() reports conflicts, it does so compatibly with
library() by using message().
* R CMD Sweave no longer cleans any files by default, compatibly
with versions of R prior to 3.1.0. There are new options
--clean, --clean=default and --clean=keepOuts.
* tools::buildVignette() and tools::buildVignettes() with clean =
FALSE no longer remove any created files. buildvignette() gains
a keep argument for more cleaning customization.
* The Bioconductor 'version' used by setRepositories() can now be
set by environment variable R_BIOC_VERSION at runtime, not just
when R is installed. (It has been stated that Bioconductor will
switch from 'version' 2.14 to 'version' 3.0 during the lifetime
of the R 3.1 series.)
* Error messages from bugs in embedded Sexpr code in Sweave
documents now report the source location.
* type.convert(), read.table() and similar read.*() functions get a
new numerals argument, specifying how numeric input is converted
when its conversion to double precision loses accuracy. The
default value, "allow.loss" allows accuracy loss, as in R
versions before 3.1.0.
* For some compilers, integer addition could overflow without a
warning. R's internal code for both integer addition and
subtraction is more robust now.
* The function determining the default number of knots for
smooth.spline() is now exported, as .nknots.smspl().
* dbeta(, a,b), pbeta(), qbeta() and rbeta() are now defined also
for a = 0, b = 0, or infinite a and b (where they typically
returned NaN before).
* Many package authors report that the RStudio graphics device does
not work correctly with their package's use of dev.new(). The
new option dev.new(noRStudioGD = TRUE) replaces the RStudio
override by the default device as selected by R itself, still
respecting environment variables R_INTERACTIVE_DEVICE and
R_DEFAULT_DEVICE.
* readRDS() now returns visibly.
* Modifying internal logical scalar constants now results in an
error instead of a warning.
* install.packages(repos = NULL) now accepts http:// or ftp:// URLs
of package archives as well as file paths, and will download as
required. In most cases repos = NULL can be deduced from the
extension of the URL.
* The warning when using partial matching with the $ operator on
data frames is now only given when
options("warnPartialMatchDollar") is TRUE.
* Package help requests like package?foo now try the package foo
whether loaded or not.
* General help requests now default to trying all loaded packages,
not just those on the search path.
* Added a new function promptImport(), to generate a help page for
a function that was imported from another package (and presumably
re-exported, or help would not be needed).
--0.19--

CHANGELOG:
0.2
---
* Added `Hashable` and `Data` support.
* Will build as full-fledged `Safe` Haskell if you configure with -f-hashable, merely `Trustworthy` otherwise.
* Allow for manual removal of the `hashable` dependency to support advanced sandbox users who explicitly want to avoid compiling certain dependencies
they know they aren't using.
We will fix bugs caused by any combination of these package flags, but the API of the package should be considered the default build
configuration with all of the package dependency flags enabled.
Update LICENSE
Upstream changes:
30 May 2014: statmod 1.4.20
- Considerable work on the inverse Gaussian functions dinvgauss(),
pinvgauss(), qinvgauss() and rinvgauss(). The parameter arguments
are changed to mean, shape and dispersion instead of mu and lambda.
The functions now include arguments lower.tail and log.p, meaning
that right-tailed probabilities can be used and probabilities can
be specified on the log-scale. Good numerical precision is
maintained in these case. The functions now respect attributes,
so that a matrix argument for example will produce a matrix result.
Checking is now done for missing values and invalid parameter
values on an element-wise basis. A technical report has been
written to describe the methodology behind qinvgauss().
- This file has been renamed to NEWS instead of changelog.txt.
- The introductory help page previously called 1.Introduction is now
named statmod-package.
13 April 2014: statmod 1.4.19
- qinvgauss() now uses a globally convergent Newton iteration, which
produces accurate values for a greater range of parameter values.
- glmnb.fit() now supports weights.
Update LICENSE
Upstream changes:
Changes in Version 1.7-11
o Extended the license from "GPL-2" to "GPL-2 | GPL-3".
o Avoid duplications in Suggests/Imports/Depends in the package's
DESCRIPTION. Use only :: instead of ::: to access certain functions
from other namespaces.
o Added as.list() methods for yearmon/yearqtr.
o Added workaround in Ops.zoo if first argument is not a zoo series
(prompted by Josh Ulrich).
o The transform() method for zoo series now does what method for
data.frame does (instead of just calling it) in order to get
non-standard evaluation.

packaged for wip.
A Scientific number is an arbitrary-precision floating-point number
represented using scientific notation.
A scientific number with coefficient c and base10Exponent e corresponds to
the Fractional number: fromInteger c * 10 ^^ e
Its primary use-case is to serve as the target of parsing floating point
numbers. Since the textual representation of floating point numbers use
scientific notation they can be efficiently parsed to a Scientific number.
Do it for all packages that
* mention perl, or
* have a directory name starting with p5-*, or
* depend on a package starting with p5-
like last time, for 5.18, where this didn't lead to complaints.
Let me know if you have any this time.
NEW FEATURES:
* type.convert() (and hence by default read.table()) returns a
character vector or factor when representing a numeric input as a
double would lose accuracy. Similarly for complex inputs.
If a file contains numeric data with unrepresentable numbers of
decimal places that are intended to be read as numeric, specify
colClasses in read.table() to be "numeric".
* tools::Rdiff(useDiff = FALSE) is closer to the POSIX definition
of diff -b (as distinct from the description in the man pages of
most systems).
* New function anyNA(), a version of any(is.na(.)) which is fast
for atomic vectors, based on a proposal by Tim Hesterberg.
* arrayInd(*, useNames = TRUE) and, analogously, which(*, arr.ind =
TRUE) now make use of names(.dimnames) when available.
* is.unsorted() now also works for raw vectors.
* The "table" method for as.data.frame() (also useful as
as.data.frame.table()) now passes sep and base arguments to
provideDimnames().
* uniroot() gets new optional arguments, notably extendInt,
allowing to auto-extend the search interval when needed. The
return value has an extra component, init.it.
* switch(f, ...) now warns when f is a factor, as this typically
happens accidentally where the useR meant to pass a character
string, but f is treated as integer (as always documented).
* The parser has been modified to use less memory.
* The way the unary operators (+ - !) handle attributes is now more
consistent. If there is no coercion, all attributes (including
class) are copied from the input to the result: otherwise only
names, dims and dimnames are.
* colorRamp() and colorRampPalette() now allow non-opaque colours
and a ramp in opacity via the new argument alpha = TRUE.
(Suggested by Alberto Krone-Martins, but optionally as there are
existing uses which expect only RGB values.)
* grid.show.layout() and grid.show.viewport() get an optional vp.ex
argument.
* There is a new function find_gs_cmd() in the tools package to
locate a GhostScript executable. (This is an enhanced version of
a previously internal function there.)
* object.size() gains a format() method.
* There is a new family, "ArialMT", for the pdf() and postscript()
devices. This will only be rendered correctly on viewers which
have access to Monotype TrueType fonts (which are sometimes
requested by journals).
* The text and PDF news files, including NEWS and NEWS.2, have been
moved to the doc directory.
* combn(x, simplify = TRUE) now gives a factor result for factor
input x (previously user error).
* Added utils::fileSnapshot() and utils::changedFiles() functions
to allow snapshots and comparison of directories of files.
* make.names(names, unique=TRUE) now tries to preserve existing
names.
* New functions cospi(x), sinpi(x), and tanpi(x), for more accurate
computation of cos(pi*x), etc, both in R and the C API. Using
these gains accuracy in some cases, e.g., inside lgamma() or
besselI().
* print.table(x, zero.print = ".") now also has an effect when x is
not integer-valued.
* There is more support to explore the system's idea of time-zone
names. Sys.timezone() tries to give the current system setting
by name (and succeeds at least on Linux, OS X, Solaris and
Windows), and OlsonNames() lists the names in the system's Olson
database. Sys.timezone(location = FALSE) gives the previous
behaviour.
* Platforms with a 64-bit time_t type are allowed to handle
conversions between the "POSIXct" and "POSIXlt" classes for
date-times outside the 32-bit range (before 1902 or after 2037):
the existing workarounds are used on other platforms. (Note that
time-zone information for post-2037 is speculative at best, and
the OS services are tested for known errors and so not used on OS
X.)
Currently time_t is usually long and hence 64-bit on Unix-alike
64-bit platforms: however it several cases the time-zone database
is 32-bit. On R for Windows it is 64-bit (for both architectures
as from this version).
* The "save.defaults" option can include a value for
compression_level.
* colSums() and friends now have support for arrays and data-frame
columns with 2^31 or more elements.
* as.factor() is faster when f is an unclassed integer vector (for
example, when called from tapply()).
* fft() now works with longer inputs, from the 12 million
previously supported up to 2 billion.
* Complex svd() now uses LAPACK subroutine ZGESDD, the complex
analogue of the routine used for the real case.
* Sweave now outputs .tex files in UTF-8 if the input encoding is
declared to be UTF-8, regardless of the local encoding. The
UTF-8 encoding may now be declared using a LaTeX comment
containing the string %\SweaveUTF8 on a line by itself.
* file.copy() gains a copy.date argument.
* Printing of date-times will make use of the time-zone
abbreviation in use at the time, if known. For example, for
Paris pre-1940 this could be LMT, PMT, WET or WEST. To enable
this, the "POSIXlt" class has an optional component "zone"
recording the abbreviation for each element.
For platforms which support it, there is also a component
"gmtoff" recording the offset from GMT where known.
* (On Windows, by default on OS X and optionally elsewhere.) The
system C function strftime has been replaced by a more
comprehensive version with closer conformance to the POSIX 2008
standard.
* dnorm(x, log = FALSE) is more accurate (but somewhat slower) for
|x| > 5.
* Some versions of the tiff() device have further compression
options.
* read.table(), readLines() and scan() have a new argument to
influence the treatment of embedded nuls.
* Avoid duplicating the right hand side values in complex
assignments when possible. This reduces copying of replacement
values in expressions such as Z$a <- a0 and ans[[i]] <- tmp: some
package code has relied on there being copies.
Also, a number of other changes to reduce copying of objects; all
contributed by or based on suggestions by Michael Lawrence.
* The fast argument of KalmanLike(), KalmanRun() and
KalmanForecast() has been replaced by update, which instead of
updating mod in place, optionally returns the updated model in an
attribute "mod" of the return value.
* arima() and makeARIMA() get a new optional argument SSinit,
allowing the choice of a different *s*tate *s*pace initialization
which has been observed to be more reliable close to
non-stationarity.
* warning() has a new argument noBreaks., to simplify
post-processing of output with options(warn = 1).
* pushBack() gains an argument encoding, to support reading of
UTF-8 characters using scan(), read.table() and related functions
in a non-UTF-8 locale.
* all.equal.list() gets a new argument use.names which by default
labels differing components by names (if they match) rather than
by integer index. Saved R output in packages may need to be
updated.
* The methods for all.equal() and attr.all.equal() now have
argument check.attributes after ... so it cannot be partially nor
positionally matched (as it has been, unintentionally).
A side effect is that some previously undetected errors of
passing empty arguments (no object between commas) to all.equal()
are detected and reported.
There are explicit checks that check.attributes is logical,
tolerance is numeric and scale is NULL or numeric. This catches
some unintended positional matching.
The message for all.equal.numeric() reports a "scaled difference"
only for scale != 1.
* all.equal() now has a "POSIXt" method replacing the "POSIXct"
method.
* The "Date" and "POSIXt" methods of seq() allows by = "quarter"
for completeness (by = "3 months" always worked).
* file.path() removes any trailing separator on Windows, where they
are invalid (although sometimes accepted). This is intended to
enhance the portability of code written by those using POSIX file
systems (where a trailing / can be used to confine path matching
to directories).
* New function agrepl() which like grepl() returns a logical
vector.
* fifo() is now supported on Windows.
* sort.list(method = "radix") now allows negative integers
* Some functionality of print.ts() is now available in
.preformat.ts() for more modularity.
* mcparallel() gains an option detach = TRUE which allows execution
of code independently of the current session. It is based on a
new estranged = TRUE argument to mcfork() which forks child
processes such that they become independent of the parent
process.
* The pdf() device omits circles and text at extremely small sizes,
since some viewers were failing on such files.
* The rightmost break for the "months", "quarters" and "years"
cases of hist.POSIXlt() has been increased by a day.
* The handling of DF[i,] <- a where i is of length 0 is improved.
* hclust() gains a new method "ward.D2" which implements Ward's
method correctly. The previous "ward" method is "ward.D" now,
with the old name still working. Thanks to research and
proposals by Pierre Legendre.
* The sunspot.month dataset has been amended and updated from the
official source, whereas the sunspots and sunspot.year datasets
will remain immutable. The documentation and source links have
been updated correspondingly.
* The summary() method for "lm" fits warns if the fit is
essentially perfect, as most of the summary may be computed
inaccurately (and with platform-dependent values).
Programmers who use summary() in order to extract just a
component which will be reliable (e.g. $cov.unscaled) should wrap
their calls in suppressWarnings().
version: 0.13
date: Mon Apr 14 11:08:45 CEST 2014
changes:
- deprecate isl_int
- improved support for multi piecewise quasi-affine expressions
- allow the user to impose a bound on the number of low-level operations
- add isl_id_to_ast_expr and isl_id_to_pw_aff
- add isl_schedule_constraints
- hide internal structure of isl_vec
- remove support for piplib
2.8 --> 2.8.1
-------------
Improvements:
- The installation procedure was updated to work with recent
NumPy versions and in a wider range of environments.
LIBSVM is an integrated software for support vector classification, (C-SVC, nu-
SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class
SVM). It supports multi-class classification.
Block-triangular LU-factorization was implemented to be used
on computing an initial factorization of the basis matrix.
A new version of the Schur-complement-based factorization
module was included in the package. Now it can be used along
with plain as well as with block-triangular LU-factorization.
Currently the following flags can be used to specify the type
of the basis matrix factorization (glp_bfcp.type):
GLP_BF_LUF + GLP_BF_FT LUF, Forrest-Tomlin update (default)
GLP_BF_LUF + GLP_BF_BG LUF, Schur complement, Bartels-Golub
update
GLP_BF_LUF + GLP_BF_GR LUF, Schur complement, Givens rotation
update
GLP_BF_BTF + GLP_BF_BG BTF, Schur complement, Bartels-Golub
update
GLP_BF_BTF + GLP_BF_GR BTF, Schur complement, Givens rotation
update
In case of GLP_BF_FT the update is applied to matrix U, while
in cases of GLP_BF_BG and GLP_BF_GR the update is applied to
the Schur complement.
Corresponding new options --luf and --btf were added to glpsol.
For more details please see a new edition of the GLPK reference
manual included in the distribution.
A minor bug (in reporting the mip solution status) was fixed.
A call to "iodbc-config --cflags" was added in configure.ac
to correctly detect iodbc flags.
FFTW 3.3.4
* New functions fftw_alignment_of (to check whether two arrays are
equally aligned for the purposes of applying a plan) and fftw_sprint_plan
(to output a description of plan to a string).
* Bugfix in fftw-wisdom-to-conf; thanks to Florian Oppermann for the
bug report.
* Fixed manual to work with texinfo-5.
* Increased timing interval on x86_64 to reduce timing errors.
* Default to Win32 threads, not pthreads, if both are present.
* Various build-script fixes.
CHANGES IN R 3.0.3:
NEW FEATURES:
* On Windows there is support for making .texi manuals using
texinfo 5.0 or later: the setting is in file
src/gnuwin32/MkRules.dist.
A packaging of the Perl script and modules for texinfo 5.2 has
been made available at <URL:
http://www.stats.ox.ac.uk/pub/Rtools/>.
* write.table() now handles matrices of 2^31 or more elements, for
those with large amounts of patience and disc space.
* There is a new function, La_version(), to report the version of
LAPACK in use.
* The HTML version of 'An Introduction to R' now has links to PNG
versions of the figures.
* There is some support to produce manuals in ebook formats. (See
doc/manual/Makefile. Suggested by Mauro Cavalcanti.)
* On a Unix-alike Sys.timezone() returns NA if the environment
variable TZ is unset, to distinguish it from an empty string
which on some OSes means the UTC time zone.
* The backtick may now be escaped in strings, to allow names
containing them to be constructed, e.g. `\``.
* read.table(), readLines() and scan() now warn when an embedded
nul is found in the input.
* KalmanForecast(fast = FALSE) is now the default, and the help
contains an example of how fast = TRUE can be used in this
version. (The usage will change in 3.1.0.)
* strptime() now checks the locale only when locale-specific
formats are used and caches the locale in use: this can halve the
time taken on OSes with slow system functions (e.g. OS X).
* strptime() and the format() methods for classes "POSIXct",
"POSIXlt" and "Date" recognize strings with marked encodings:
this allows, for example, UTF-8 French month names to be read on
(French) Windows.
* iconv(to = "utf8") is now accepted on all platforms (some
implementations did already, but GNU libiconv did not: however
converted strings were not marked as being in UTF-8). The
official name, "UTF-8" is still preferred.
* available.packages() is better protected against corrupt metadata
files.
* Finalizers are marked to be run at garbage collection, but run
only at a somewhat safer later time (when interrupts are
checked). This circumvents some problems with finalizers running
arbitrary code during garbage collection (the known instances
being running options() and (C-level) path.expand()
re-entrantly).

- Update reference for permp().
- bug fix to elda() so that it returns NA for the tests instead of
giving an error when the Fisher information for the slope isNA.
- Exact roles of authors specified in DESCRIPTION file.
- All usage lines in help files wrapped at 90 characters to ensure
that code is not truncated in pdf manual.
Upstream changes:
(But no changes for 0.4.7)
Version 0.4-6 2013/10/30
Added function dasytriangular for the density of asymmetric triangular distribution as described in Mardia (1972)
In this version two functions are available for evaluating the median (medianCircular which allows for the dispersion para
meter and median.circular with only the median reported), however medianCircular is deprecated and it will be removed in t
he next releases.
Added mean.circular.c to calculate the circular mean in C language.
New algorithm for circular median. The implementation is in C language.
Added function for Hodges Lehmann estimate of the median for circular and non circular data.
Several bugs fixed.
Upstream changes:
Changes in Version 1.7-11
o Extended the license from "GPL-2" to "GPL-2 | GPL-3".
o Avoid duplications in Suggests/Imports/Depends in the package's
DESCRIPTION. Use only :: instead of ::: to access certain functions
from other namespaces.
o Added as.list() methods for yearmon/yearqtr.
o Added workaround in Ops.zoo if first argument is not a zoo series
(prompted by Josh Ulrich).
o The transform() method for zoo series now does what method for
data.frame does (instead of just calling it) in order to get
non-standard evaluation.
* New, no 2to3, Python 2 and Python 3 are supported by a common code base.
* New, gufuncs for linear algebra, enabling operations on stacked arrays.
* New, inplace fancy indexing for ufuncs with the ``.at`` method.
* New, ``partition`` function, partial sorting via selection for fast median.
* New, ``nanmean``, ``nanvar``, and ``nanstd`` functions skipping NaNs.
* New, ``full`` and ``full_like`` functions to create value initialized arrays.
* New, ``PyUFunc_RegisterLoopForDescr``, better ufunc support for user dtypes.
* Numerous performance improvements in many areas.
* Support for Python versions 2.4 and 2.5 has been dropped.
* Support for SCons has been removed.
* added Symmetric/Hermitian LDLT factorization routines with rook pivoting algorithm
* 2-by-1 CSD to be used for tall and skinny matrix with orthonormal columns (in LAPCK 3.4.0, we already integrated CSD of a full square orthogonal matrix)
* New stopping criteria for balancing.
Perl extension for Munkres' solution to classical Assignment problem
for square and rectangular matrices. This module extends the solution
of Assignment problem for square matrices to rectangular matrices by
padding zeros. Thus a rectangular matrix is converted to square matrix
by padding necessary zeros.
* The API routine glp_read_mps was changed to remove free rows.
* A bug was fixed in the API routine glp_read_lp.
* The zlib compression library used by some GLPK routines and
included in the package was downgraded from 1.2.7 to 1.2.5 (as
in GLPK 4.50) because of addressability bugs on some 64-bit
platforms.
* A bug was fixed in a routine that reads gzipped files.
* Two API routines glp_get_it_cnt and glp_set_it_cnt were added.
* All obsolete GLPK API routines (prefixed with lpx) were removed
from the package.
* A set of routines that simulate the old GLPK API (as defined
in 4.48) were added; see examples/oldapi/api/lpx.c.
* A namespace bug was fixed in the SQL table drive module.
* The NEWS files have been re-organized.
This file contains news for R >= 3.0.0: news for the 0.x.y, 1.x.y
and 2.x.y releases is in files NEWS.0, NEWS.1 and NEWS.2. The
latter files are now installed when R is installed. An HTML
version of news from 2.10.0 to 2.15.3 is available as
doc/html/NEWS.2.html.
* sum() for integer arguments now uses an integer accumulator of at
least 64 bits and so will be more accurate in the very rare case
that a cumulative sum exceeds 2^53 (necessarily summing more than
4 million elements).
* The example() and tools::Rd2ex() functions now have parameters to
allow them to ignore \dontrun markup in examples. (Suggested by
Peter Solymos.)
* str(x) is considerably faster for very large lists, or factors
with 100,000 levels, the latter as in PR#15337.
* col2rgb() now converts factors to character strings not integer
codes (suggested by Bryan Hanson).
* tail(warnings()) now works, via the new `[` method.
* There is now support for the LaTeX style file zi4.sty which has
in some distributions replaced inconsolata.sty.
* unlist(x) now typically returns all non-list xs unchanged, not
just the "vector" ones. Consequently, format(lst) now also works
when the list lst has non-vector elements.
* The tools::getVignetteInfo() function has been added to give
information about installed vignettes.
* New assertCondition(), etc. utilities in tools, useful for
testing.
* Profiling now records non-inlined calls from byte-compiled code
to BUILTIN functions.
* Various functions in stats and elsewhere that use non-standard
evaluation are now more careful to follow the namespace scoping
rules. E.g. stats::lm() can now find stats::model.frame() even
if stats is not on the search path or if some package defines a
function of that name.
* If an invalid/corrupt .Random.seed object is encountered in the
workspace it is ignored with a warning rather than giving an
error. (This allows R itself to rely on a working RNG, e.g. to
choose a random port.)
* seq() and seq.int() give more explicit error messages if called
with invalid (e.g. NaN) inputs.
* When parse() finds a syntax error, it now makes partial parse
information available up to the location of the error. (Request
of Reijo Sund.)
* Methods invoked by NextMethod() had a different dynamic parent to
the generic. This was causing trouble where S3 methods invoked
via lazy evaluation could lose track of their generic.
(PR#15267)
* Code for the negative binomial distribution now treats the case
size == 0 as a one-point distribution at zero.
* abbreviate() handles without warning non-ASCII input strings
which require no abbreviation.
* read.dcf() no longer has a limit of 8191 bytes per line. (Wish of
PR#15250.)
* formatC(x) no longer copies the class of x to the result, to
avoid misuse creating invalid objects as in PR#15303. A warning
is given if a class is discarded.
* Dataset npk has been copied from MASS to allow more tests to be
run without recommended packages being installed.
* The initialization of the regression coefficients for
non-degenerate differenced models in arima() has been changed and
in some examples avoids a local maximum. (PR#15396)
* termplot() now has an argument transform.x to control the display
of individual terms in the plot. (PR#15329)
* format() now supports digits = 0, to display nsmall decimal
places.
* There is a new read-only par() parameter called "page", which
returns a logical value indicating whether the next plot.new()
call will start a new page.
* Processing Sweave and Rd documents to PDF now renders backticks
* utils::modifyList() gets a new argument keep.null allowing NULL
components in the replacement to be retained, instead of causing
corresponding components to be deleted.
* tools::pkgVignettes() gains argument check; if set to TRUE, it
will warn when it appears a vignette requests a non-existent
vignette engine.
--------------------------------------------------------------------------
NEWS for version 1.1 (released on October 28, 2013)
--------------------------------------------------------------------------
New and Changed Features
========================
o Added a new operator on polyhedra: the positive time elapse.
o In the Java language interface:
- The constraint/generator/... system classes now extend the ArrayList
generic container (rather than Vector);
- Variable objects are now built from a long (rather than int) value,
thereby matching the type used elsewhere for space dimensions;
- added new static method to Variable class
void setStringifier(Variable_Stringifier)
where Variable_Stringifier is an interface allowing for
customization of the output routine for variable's names
(see example in interfaces/Java/tests/Variable_Output_test1.java);
- added value NOT_EQUAL to enumeration Relation_Symbol.
Bugfixes
========
o Portability improved.
o Fixed a precision regression in Polyhedron method
void drop_some_non_integer_points(const Variables_Set&,
Complexity_Class);
o In the Java language interface, fixed a C++/Java conversion error
whereby the construction of a valid Variable object in JNI code
was leading to an exception being thrown. The bug has only been
observed on 32-bit builds.
o In the Java interface, fixed declaration of methods
void drop_some_non_integer_points(...);
so as to accept a Complexity_Class enum value.
o Fixed an issue in method MIP_Problem::OK() whereby the method
was trying to enforce a non-invariant condition.
--------------------------------------------------------------------------
NEWS for version 1.0 (released on June 28, 2012)
--------------------------------------------------------------------------
New and Changed Features
========================
o Significant improvements have been obtained in both time and space
resource usage by the definition of data structures and algorithms
for the case of "sparse rows", i.e., sequences of coefficients
where most of the values are zero.
o The library fully supports two different representations for rows:
the "dense" representation is an array-like representation tailored
to sequences having most of their coefficients different from zero;
the "sparse" representation saves memory space (as well as CPU
cycles) when most of the coefficients in the sequence are zero.
o A generic interface allows for a seamless interaction between the
dense and the sparse row representation. Most library entities
(linear expressions, constraints, generators, congruences, and
their systems) can be built using either representation, specified
as a constructor's argument.
o As a by-product of this sparse/dense refactoring work, efficiency
improvements have been obtained even for those computations that
are still based on the dense row representation.
o Reasonable default values for the row representation are provided
for each library entity, automatically leading to significant
memory space savings even in old client/library code, e.g., when
dealing with constraint systems describing weakly relational
abstractions such as boxes and octagonal shapes.
o If desired, these default values can be customized to user's needs
by changing just a few lines of library code. For instance, the
constraint systems stored inside C_Polyhedron and NNC_Polyhedron
objects can be made to use the sparse representation by just
changing the following line in Polyhedron.defs.hh:
static const Representation default_con_sys_repr = DENSE;
to become
static const Representation default_con_sys_repr = SPARSE;
Bugfixes
========
o Fixed a bug affecting methods
bool BD_Shape<T>::contains(const BD_Shape& y) const;
bool Octagonal_Shape<T>::contains(const Octagonal_Shape& y) const;
whereby the wrong result was obtained when *this is an empty
weakly-relational shape and y is not empty.
o Fixed a bug affecting the PIP solver whereby a wrong result could have
been obtained if the input constraint system contained multiple linear
equality constraints.
--------------------------------------------------------------------------
NEWS for version 0.12.1 (released on April 16, 2012)
--------------------------------------------------------------------------
New and Changed Features
========================
o In the C, Java, OCaml and Prolog interfaces, modified the signature
of the function/method/predicate for setting the deterministic timeout
threshold. The new interfaces take two input values, named `unscaled'
and `scale', that are used to compute the threshold value as
`unscaled * 2^scale'.
o Added new Box<ITV> methods
bool has_upper_bound(Variable var,
Coefficient& n, Coefficient& d, bool& closed) const;
bool has_lower_bound(Variable var,
Coefficient& n, Coefficient& d, bool& closed) const;
to query a non-empty box for the existence and value of its upper/lower
bound on variable `var'. The methods have been also added to all the
available language interfaces.
o Two BibTeX databases of papers related to the Parma Polyhedra Library
have been added to the distribution (in the `doc' directory).
Bugfixes
========
o Restored the support for deterministic timeouts in the PIP solver
(it was removed by accident in PPL 0.12).
o Minor documentation fixes.
o Portability improved.
--------------------------------------------------------------------------
NEWS for version 0.12 (released on February 27, 2012)
--------------------------------------------------------------------------
New and Changed Features
========================
o New configure options `--with-gmp=DIR', `--with-gmp-include=DIR' and
`--with-gmp-lib=DIR' supersede the (now removed) option
`--with-gmp-prefix'. (The old option never really worked; hopefully
this is the last change in this area.)
o New configuration option `--disable-documentation'. When specified
no new documentation is built: only the documentation already present
in the source tree is installed upon `make install'.
o The resolution process for PIP_Problem now better exploits the
integrality of parameters to simplify the newly generated tautological
constraints, the splitting constraints of decision nodes, and the
expressions defining artificial parameters.
o The implementations of the MIP and PIP solvers are based on a new
data structure leading to significant space and time savings when
the tableau matrix is sparse; the benchmarks of the ppl_lpsol demo
show an improvement on the average case, that grows when the toughest
tests in the benchmark suite are considered.
o When the `--check' option is used, the input data for demo ppl_lpsol
is perturbed the same way as GLPK does, thereby allowing for a
meaningful comparison of the results obtained.
o The input routine for PPL numeric datatypes has been extended to
accept the ISO9899 (C99) hexadecimal floating constant syntax.
o The Parma Watchdog Library has been merged into the
Parma Polyhedra Library.
Bugfixes
========
o Corrected a precision bug in methods
Box<ITV>::upper_bound_assign(const Box&)
