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. `\``. (PR#15621)
* read.table(), readLines() and scan() now warn when an embedded
nul is found in the input. (Related to PR#15625 which was
puzzled by the behaviour in this unsupported case.)
* (Windows only.) file.symlink() works around the undocumented
restriction of the Windows system call to backslashes. (Wish of
PR#15631.)
* 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. (A recurring problem with Debian package shogun-r:
PR#14713.)
* 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).
INSTALLATION and INCLUDED SOFTWARE:
* The included version of PCRE has been updated to 8.34. This
fixes bugs and makes the behaviour closer to Perl 5.18. In
particular, the concept of 'space' includes VT and hence agrees
with POSIX's.
PACKAGE INSTALLATION:
* The new field SysDataCompression in the DESCRIPTION file allows
user control over the compression used for sysdata.rda objects in
the lazy-load database.
* install.packages(dependencies = value) for value = NA (the
default) or value = TRUE omits packages only in LinkingTo for
binary package installs.
C-LEVEL FACILITIES:
* The long undocumented remapping of rround() to Rf_fround() in
header Rmath.h is now formally deprecated: use fround() directly.
* Remapping of prec() and trunc() in the Rmath.h header has been
disabled in C++ code (it has caused breakage with libc++
headers).
BUG FIXES:
* getParseData() truncated the imaginary part of complex number
constants. (Reported by Yihui Xie.)
* dbeta(x, a, b) with a or b within a factor of 2 of the largest
representable number could infinite-loop. (Reported by Ioannis
Kosmidis.)
* provideDimnames() failed for arrays with a 0 dimension.
(PR#15465)
* rbind() and cbind() did not handle list objects correctly.
(PR#15468)
* replayPlot() now checks if it is replaying a plot from the same
session.
* rasterImage() and grid.raster() now give error on an empty
(zero-length) raster. (Reported by Ben North.)
* plot.lm() would sometimes scramble the labels in plot type 5.
(PR#15458 and PR#14837)
* min() did not handle NA_character_ values properly. (Reported by
Magnus Thor Torfason.)
* (Windows only.) readRegistry() would duplicate default values
for keys. (PR#15455)
* str(..., strict.width = "cut") did not handle it properly when
more than one line needed to be cut. (Reported by Gerrit
Eichner.)
* Removing subclass back-references when S4 classes were removed or
their namespace unloaded had several bugs (e.g., PR#15481).
* aggregate() could fail when there were too many levels present in
the by argument. (PR#15004)
* namespaceImportFrom() needed to detect primitive functions when
checking for duplicated imports (reported by Karl Forner).
* getGraphicsEvent() did not exit when a user closed the graphics
window. (PR#15208)
* Errors in vignettes were not always captured and displayed
properly. (PR#15495)
* contour() could fail when dealing with extremely small z values.
(PR#15454)
* Several functions did not handle zero-length vectors properly,
including browseEnv(), format(), gl(), relist() and
summary.data.frame(). (E.g., PR#15499)
* Sweave() did not restore the R output to the console if it was
interrupted by a user in the middle of evaluating a code chunk.
(Reported by Michael Sumner.)
* Fake installs of packages with vignettes work again.
* Illegal characters in the input caused parse() (and thus
source()) to segfault. (PR#15518)
* The nonsensical use of nmax = 1 in duplicated() or unique() is
now silently ignored.
* qcauchy(p, *) is now fully accurate even when p is very close to
1. (PR#15521)
* The validmu() and valideta() functions in the standard glm()
families now also report non-finite values, rather than failing.
* Saved vignette results (in a .Rout.save file) were not being
compared to the new ones during R CMD check.
* Double-clicking outside of the list box (e.g. on the scrollbar)
of a Tk listbox widget generated by tk_select.list() no longer
causes the window to close. (PR#15407)
* Improved handling of edge cases in parallel::splitindices().
(PR#15552)
* HTML display of results from help.search() and ?? sometimes
contained badly constructed links.
* c() and related functions such as unlist() converted raw vectors
to invalid logical vectors. (PR#15535)
* (Windows only) When a call to system2() specified one of stdin,
stdout or stderr to be a file, but the command was not found
(e.g. it contained its arguments, or the program was not on the
PATH), it left the file open and unusable until R terminated.
(Reported by Mathew McLean.)
* The bmp() device was not recording res = NA correctly: it is now
recorded as 72 ppi.
* Several potential problems with compiler-specific behaviour have
been identified using the 'Undefined Behaviour Sanitizer' in
conjunction with the clang compiler.
* hcl() now honours NA inputs (previously they were mapped to
black).
* Some translations in base packages were being looked up in the
main catalog rather than that for the package.
* As a result of the 3.0.2 change about 'the last second before the
epoch', most conversions which should have given NA returned that
time. (The platforms affected include Linux and OS X, but not
Windows nor Solaris.)
* rowsum() has more support for matrices and dataframes with 2^31
or more elements. (PR#15587)
* predict(<lm object>, interval = "confidence", scale
<something>) now works. (PR#15564)
* The bug fix in 3.0.2 for PR#15411 was too aggressive, and
sometimes removed spaces that should not have been removed.
(PR#15583)
* Running R code in a tcltk callback failed to set the busy flag,
which will be needed to tell OS X not to 'App Nap'.
* The code for date-times before 1902 assumed that the offset from
GMT in 1902 was a whole number of minutes: that was not true of
Paris (as recorded on some platforms).
* Using Sys.setlocale to set LC_NUMERIC to "C" (to restore the
sane
behavior) no longer gives a warning.
* deparse() now deparses complex vectors in a way that re-parses to
the original values. (PR#15534, patch based on code submitted by
Alex Bertram.)
* In some extreme cases (more than 10^15) integer inputs to
dpqrxxx() functions might have been rounded up by one (with a
warning about being non-integer). (PR#15624)
* Plotting symbol pch = 14 had the triangle upside down on some
devices (typically screen devices). The triangle is supposed to
be point up. (Reported by Bill Venables.)
* getSrcref() did not work on method definitions if
rematchDefinition() had been used.
* KalmanForecast(fast = FALSE) reported a (harmless) stack
imbalance.
* The count of observations used by KalmanRun() did not take
missing values into account.
* In locales where the abbreviated name of one month is a partial
match for the full name of a later one, the %B format in
strptime() could fail. An example was French on OS X, where juin
is abbreviated to jui and partially matches juillet. Similarly
for weekday names.
* pbeta(x, a, b, log.p = TRUE) sometimes underflowed to zero for
very small and very differently sized a, b. (PR#15641)
* approx() and approxfun() now handle infinite values with the
"constant" method. (PR#15655)
* stripchart() again respects reversed limits in xlim and ylim.
(PR#15664)
