CHANGES IN R 3.6.0:
SIGNIFICANT USER-VISIBLE CHANGES:
* Serialization format version 3 becomes the default for
serialization and saving of the workspace (save(), serialize(),
saveRDS(), compiler::cmpfile()). Serialized data in format 3
cannot be read by versions of R prior to version 3.5.0.
Serialization format version 2 is still supported and can be
selected by version = 2 in the save/serialization functions. The
default can be changed back for the whole R session by setting
environment variables R_DEFAULT_SAVE_VERSION and
R_DEFAULT_SERIALIZE_VERSION to 2. For maximal
back-compatibility, files vignette.rds and partial.rdb generated
by R CMD build are in serialization format version 2, and resave
by default produces files in serialization format version 2
(unless the original is already in format version 3).
* The default method for generating from a discrete uniform
distribution (used in sample(), for instance) has been changed.
This addresses the fact, pointed out by Ottoboni and Stark, that
the previous method made sample() noticeably non-uniform on large
populations. See PR#17494 for a discussion. The previous method
can be requested using RNGkind() or RNGversion() if necessary for
reproduction of old results. Thanks to Duncan Murdoch for
contributing the patch and Gabe Becker for further assistance.
The output of RNGkind() has been changed to also return the
'kind' used by sample().
NEW FEATURES:
* Sys.setFileTime() has been vectorized so arguments path and time
of length greater than one are now supported.
* axis() gets new option gap.axis = NA for specifying a
multiplication factor for the minimal "gap" (distance) between
axis labels drawn. Its default is 1 for labels _parallel_ to the
axis, and 0.25 for perpendicular ones.
Perpendicular labels no longer overlap, fixing bug PR#17384.
* The default method of plot() gains new arguments xgap.axis = NA
and ygap.axis = NA to be passed to the x- and y- axis(..,
gap.axis=*) calls.
* removeSource() now works not only for functions but also for some
language objects.
* as.call(), rep.int(), rep_len() and nchar() dispatch internally.
* is(object, class2) looks for class2 in the calling namespace
after looking in the namespace of class(object).
* extendrange(.., f) with a length-2 f now extends separately to
the left and the right.
* lengths() dispatches internally to S4 methods.
* download.file() on Windows now uses URLdecode() to determine the
file extension, and uses binary transfer (mode = "wb") also for
file extension .rds.
The help page for download.file() now contains the same
information on all platforms.
* Setting C locale for collation _via_ environment variables LC_ALL
and LC_COLLATE and _via_ a call to Sys.setlocale() now takes
precedence over environment variable R_ICU_LOCALE.
* There is a new function, nullfile(), to give the file name of the
null system device (e.g., /dev/null) on the current platform.
* There are two new options, keep.parse.data and
keep.parse.data.pkgs, which control whether parse data are
included into sources when keep.source or keep.source.pkgs is
TRUE. By default, keep.parse.data.pkgs is now FALSE, which
changes previous behavior and significantly reduces space and
time overhead when sources are kept when installing packages.
* In rapply(x, ..), x can also be "list-like" and of length >
2^{31}.
* trimws() gets new optional whitespace argument, allowing more
extensive definitions of "space", such as including Unicode
spaces (as wished in PR#17431).
* weighted.mean() no longer coerces the weights to a double/numeric
vector, since sum() now handles integer overflow. This makes
weighted.mean() more polymorphic and endomorphic, but be aware
that the results are no longer guaranteed to be a vector of type
double.
* When loading namespaces, S3 method registrations which overwrite
previous registrations are now noted by default (using
packageStartupMessage()).
* compiler::cmpfile() gains a version argument, for use when the
output file should be saved in serialization format 2.
* The axis labeling in the default method of pairs() may now be
toggled by new options horOdd and verOdd.
* (Not Windows nor macOS.) Package tcltk now supports an
environment variable R_DONT_USE_TK which if set disables Tk
initialization. This is intended for use to circumvent errors in
loading the package, e.g. with recent Linux running under an
address sanitizer.
* The numeric method of all.equal() gets optional arguments countEQ
and formatFUN. If countEQ is true, the mean error is more
sensible when many entries are *eq*ual.
* outer(x,y, FUN = "*") is more efficient using tcrossprod(u,v)
instead of u %*% t(v).
* vcov(<mlm>) is more efficient via new optional arguments in
summary.mlm().
* The default method of summary() gets an option to choose the
_kind_ of quantile()s to use; wish of PR#17438.
* Fitting multiple linear models _via_ lm() does work with _matrix_
offsets, as suggested in PR#17407.
* The new functions mem.maxVSize() and mem.maxMSize() allow the
maximal size of the vector heap and the maximal number of nodes
allowed in the current R process to be queried and set.
* news() gains support for NEWS.md files.
* An effort has been started to have our reference manuals, i.e.,
all help pages. show platform-independent information (rather
than Windows or Unix-alike specifics visible only on that
platform). Consequently, the Windows version of X11() / x11()
got identical formal arguments to the Unix one.
* sessionInfo()$running has been factored out in a new variable
osVersion.
* slice.index() now also works for multi-dimensional margins.
* untar() used with an external tar command assumes this supports
decompression including xz and automagically detecting the
compression type. This has been true of all mainstream
implementations since 2009 (for GNU tar, since version 1.22):
older implementations are still supported _via_ the new argument
support_old_tars whose default is controlled by environment
variable R_SUPPORT_OLD_TARS. (It looks like NetBSD and OpenBSD
have 'older' tar commands for this purpose.)
* The new function asplit() allow splitting an array or matrix by
its margins.
* New functions errorCondition() and warningCondition() provide a
convenient way to create structured error and warning objects.
.Deprecated() now signals a warning of class
"deprecatedWarning",
and .Defunct() now signals an error of class "defunctError".
* Many 'package not found' errors are now signaled as errors of
class "packageNotFoundError".
* As an experimental feature, when loadNamespace() fails because
the requested package is not available the error is initially
signaled with a retry_loadNamespace restart available. This
allows a calling handler to try to install the package and
continue.
* S3method() directives in NAMESPACE can now also be used to
perform _delayed_ S3 method registration.
* Experimentally, setting environment variable
_R_CHECK_LENGTH_1_LOGIC2_ will lead to warnings (or errors if the
variable is set to a 'true' value) when && or || encounter
and
use arguments of length more than one.
* Added "lines" and "chars" coordinate systems to
grconvertX() and
grconvertY().
* getOption() is more efficient notably for the rare case when
called with two arguments, from several contributors in PR#17394.
* In .col(dim) and .row(dim), dim now may also be an integer-valued
"double".
* sQuote() and dQuote() get an explicit q argument with obvious
default instead of using getOption("fancyQuotes") implicitly and
unconditionally.
* unzip() can list archives with comments and with spaces in file
names even using an external unzip command.
* Command line completion has a new setting rc.settings(dots FALSE) to
remove ... from the list of possible function
arguments.
* library() no longer checks packages with compiled code match
R.version$platform. loadNamespace() never has, and increasingly
the 'canonical name' does not reflect the important
characteristics of compiled code.
* The primitive functions drop() and unclass() now avoid
duplicating their data for atomic vectors that are large enough,
by returning ALTREP wrapper objects with adjusted attributes.
R-level assignments to change attributes will also use wrapper
objects to avoid duplicating data for larger atomic vectors. R
functions like structure() and unname() will therefore not
duplicate data in these settings. Generic vectors as produced by
list() are not yet covered by this optimization but may be in due
course.
* In formals(), envir becomes an optional argument instead of being
hardwired.
* Instead of signalling an error for an invalid S4 object x, str(x)
now gives a warning and subsequently still shows most parts of x,
e.g., when slots are missing.
* gamma(x) and lgamma(x) no longer warn when correctly returning
Inf or underflowing to zero. This helps maximum likelihood and
similar computations.
* convertColor() is now vectorized, so a lot faster for converting
many colours at once. The new argument vectorized to
colorConverter() ensures that non-vectorized colour converters
still work. (Thanks to Brodie Gaslam.)
* download.file() and url() get new argument headers for custom
HTTP headers, e.g., allowing to perform basic http
authentication, thanks to a patch contributed by G'abor Cs'ardi.
* File-based connection functions file(), gzfile(), bzfile() and
xzfile() now signal an error when used on a directory.
* For approx(), splinefun() _etc_, a new setting ties
c("ordered", <fun>) allows skipping the sorting and still treat
ties.
* format(x) gives a more user friendly error message in the case
where no method is defined. A minimal method is provided in
format.default(x) when isS4(x) is true.
* which(x) now also works when x is a long vector, thanks to
Suharto Anggono's PR#17201. *NB*: this may return a double
result, breaking the previous guarantee of an integer result.
* seq.default() is more careful to return an integer (as opposed to
double) result when its arguments are large and/or classed
objects; see comment #9 of Suharto Anggono's PR#17497.
* The plot() method for lm and glm fits, plot.lm(), gains a new
option iter.smooth with a default of 0 for binomial fits, no
longer down-weighting when smoothing the residuals.
* zip() passes its list of files _via_ standard input to the
external command when too long for the command line (on some
platforms).
* data() gains an overwrite argument.
* t.test() now also returns the standard error (in list component
stderr).
* model.matrix(*, contrasts.arg = CC) now warns about invalid
contrasts.args.
* Performance of substr() and substring() has been improved.
* stopifnot() has been simplified thanks to Suharto Anggono's
proposals to become considerably faster for cheap expressions.
* The default 'user agent' has been changed when accessing http://
and https:// sites using libcurl. (A site was found which caused
libcurl to infinite-loop with the previous default.)
* sessionInfo() now also contains RNGkind() and prints it when it
differs from the default; based on a proposal and patch by Gabe
Becker in PR#17535. Also, RNGversion(getRversion()) works
directly.
* library() and require() now allow more control over handling
search path conflicts when packages are attached. The policy is
controlled by the new conflicts.policy option.
* barplot() gets a formula method, thanks to a patch proposal by
Arni Magnusson in PR#17521.
* pmax() and pmin(x) now also work for long vectors, thanks to
Suharto Anggono's PR#17533.
* bxp() now warns when omitting duplicated arguments.
* New hcl.colors() function to provide wide range of HCL-based
colour palettes with much better perceptual properties than the
existing RGB/HSV-based palettes like rainbow().
Also a new hcl.pals() function to list available palette names
for hcl.colors().
Contributed by Achim Zeileis.
* The default colours for image() and filled.contour() are now
based on hcl.colors().
* The palette-generating functions rainbow(), gray.colors(), etc.
get a new rev argument to facilitate reversing the order of
colors.
* New str2lang() and str2expression() as streamlined versions of
parse(text=., keep.source=FALSE) allow to abstract typical call
constructions, e.g., in formula manipulations. (Somewhat
experimental)
* Add update_PACKAGES() for incrementally updating a package
repository index, instead of rebuilding the index from scratch.
Thanks to Gabe Becker in PR#17544 for the patch, based on part of
his switchr package.
INSTALLATION on a UNIX-ALIKE:
* The options selected for the C++ compiler default to the C++11
standard if supported, otherwise to the C++98 standard.
* Visibility macros such as C_VISIBILITY can now be user-set
(including to empty), e.g. in config.site.
* Macro FCLIBS, which has sometimes been needed on Solaris, has
been renamed to FCLIBS_XTRA.
* Macro F77 is always set to the value of FC, so the latter should
be set to user-select the Fortran compiler for both fixed-form
and free-form Fortran. In particular, gfortran is now the first
choice for F77, not f95.
Macros FFLAGS and FCFLAGS remain distinct to allow for a compiler
which needs a flag to select free- or fixed-form Fortran (most
use the source-file extension to choose: .f is fixed-form and
.f90 and .f95 are free-form).
If only one of them is set, its value is used for both.
* The special-casing of CFLAGS, CXXFLAGS and FFLAGS for Intel
compilers on Linux has been removed: we do not have recent
experience but the generic defaults now chosen are the same as
those previously special-cased for x86_64.
If necessary, override the defaults on the configure command line
or in file config.site.
* Long-untested configure support for HP-UX and very old versions
of Linux has been removed.
* configure --with-blas (without specifying a value) includes
OpenBLAS in its search (before ATLAS and a generic BLAS). This
follows recent versions of the ax_blas autoconf macro.
* The configure macro MAKEINFO has been updated to TEXI2ANY.
* Support for make install-strip has been enhanced.
PACKAGE INSTALLATION:
* Source package installation is by default 'staged': the package
is installed into a temporary location under the final library
directory and moved into place once the installation is complete.
The benefit is that partially-installed packages are hidden from
other R sessions.
The overall default is set by environment variable
R_INSTALL_STAGED. R CMD INSTALL has new options --staged-install
and --no-staged-install, and packages can use the StagedInstall
field in their DESCRIPTION file to opt out. (That opt-out is a
temporary measure which may be withdrawn in future.)
Staged installation requires either --pkglock or --lock, one of
which is used by default.
* The interpretation of source code with extension .f is changing.
Previously this denoted FORTRAN 77 code, but current compilers no
longer have a FORTRAN 77 mode and interpret it as 'fixed-form'
Fortran 90 (or later where supported) code. Extensions .f90 and
.f95 continue to indicate 'free-form' Fortran code.
Legal FORTRAN 77 code is also legal fixed-form Fortran 9x;
however this change legitimizes the use of later features, in
particular to replace features marked 'obsolescent' in Fortran 90
and 'deleted' in Fortran 2018 which gfortran 8.x and later warn
about.
* Packages containing files in the src directory with extensions
.f90 or .f95 are now linked using the C or C++ compiler rather
than the Fortran 9x compiler. This is consistent with fixed-form
Fortran code and allows mixing of C++ and free-form Fortran on
most platforms.
Consequentially, a package which includes free-form Fortran 9x
code which uses OpenMP should include SHLIB_OPENMP_CFLAGS (or the
CXXFLAGS version if they also include C++ code) in PKG_LIBS
rather than SHLIB_OPENMP_FCFLAGS - fortunately on almost all
current platforms they are the same flag.
* Macro PKG_FFLAGS will be used for the compilation of both
fixed-form and free-form Fortran code unless PKG_FCFLAGS is also
set (in src/Makevars or src/Makevars.win).
* The make macro F_VISIBILITY is now preferred for both fixed-form
and free-form Fortran, for use in src/Makevars and similar.
* R CMD INSTALL gains a new option --strip which (where supported)
strips installed shared object(s): this can also be achieved by
setting the environment variable _R_SHLIB_STRIP_ to a true value.
The new option --strip-lib attempts stripping of static and
shared libraries installed under lib.
These are most useful on platforms using GNU binutils (such as
Linux) and compiling with -g flags.
* There is more support for installing UTF-8-encoded packages in a
strict Latin-1 locale (and probably for other Latin locales):
non-ASCII comments in R code (and NAMESPACE files) are worked
around better.
UTILITIES:
* R CMD check now optionally checks makefiles for correct and
portable use of the SHLIB_OPENMP_*FLAGS macros.
* R CMD check now evaluates \Sexpr{} expressions (including those
in macros) before checking the contents of Rd files and so
detects issues both in evaluating the expressions and in the
expanded contents.
* R CMD check now lists missing packages separated by commas and
with regular quotes such as to be useful as argument in calling
install.packages(c(..)); from a suggestion by Marcel Ramos.
* tools::Rd2latex() now uses UTF-8 as its default output encoding.
* R CMD check now checks line endings of files with extension .hpp
and those under inst/include. The check now includes that a
non-empty file is terminated with a newline.
R CMD build will correct line endings in such files.
* R CMD check now tries re-building all vignettes rather than
stopping at the first error: whilst doing so it adds 'bookmarks'
to the log. By default (see the 'R Internals' manual) it
re-builds each vignette in a separate process.
It now checks for duplicated vignette titles (also known as
'index entries'): they are used as hyperlinks on CRAN package
pages and so do need to be unique.
* R CMD check has more comprehensive checks on the data directory
and the functioning of data() in a package.
* R CMD check now checks autoconf-generated configure files have
their corresponding source files, including optionally attempting
to regenerate them on platforms with autoreconf.
* R CMD build has a new option --compression to select the
compression used for the tarball.
* R CMD build now removes src/*.mod files on all platforms.
C-LEVEL FACILITIES:
* New pointer protection C functions R_PreserveInMSet and
R_ReleaseFromMSet have been introduced to replace UNPROTECT_PTR,
which is not safe to mix with UNPROTECT (and with
PROTECT_WITH_INDEX). Intended for use in parsers only.
* NAMEDMAX has been raised to 7 to allow further protection of
intermediate results from (usually ill-advised) assignments in
arguments to BUILTIN functions. Properly written package code
should not be affected.
* R_unif_index is now considered to be part of the C API.
* R_GetCurrentEnv() allows C code to retrieve the current
environment.
DEPRECATED AND DEFUNCT:
* Argument compressed of untar() is deprecated - it is only used
for external tar commands which increasingly for extraction
auto-detect compression and ignore their zjJ flags.
* var(f) and hence sd(f) now give an error for factor arguments;
they gave a deprecation warning since R 3.2.3, PR#16564.
* Package tools' vignetteDepends() has been deprecated (it called a
function deprecated since Feb 2016), being partly replaced by
newly exported vignetteInfo().
* The f77_f2c script has been removed: it no longer sufficed to
compile the .f files in R.
* The deprecated legacy support of make macros such as CXX1X has
been removed: use the CXX11 forms instead.
* Make macro F77_VISIBILITY is deprecated in favour of
F_VISIBILITY.
* Make macros F77, FCPIFCPLAGS and SHLIB_OPENMP_FCFLAGS are
deprecated in favour of FC, FPICFLAGS and SHLIB_OPENMP_FFLAGS
respectively.
* $.data.frame had become an expensive version of the default
method, so has been removed. (Thanks to Radford Neal for picking
this up and to Duncan Murdoch for providing a patch.)
BUG FIXES:
* replayPlot(r) now also works in the same R session when r has
been "reproduced" from serialization, typically after saving to
and reading from an RDS file.
* substr() and substring() now signal an error when the input is
invalid UTF-8.
* file.copy() now works also when its argument to is of length
greater than one.
* mantelhaen.test() no longer suffers from integer overflow in
largish cases, thanks to Ben Bolker's PR#17383.
* Calling setGeneric("foo") in a package no longer fails when the
enclosing environment of the implicit generic foo() is
.GlobalEnv.
* untar(file("<some>.tar.gz"), *) now gives a better error
message,
suggesting to use gzfile() instead.
* Method dispatch uses more relevant environments when looking up
class definitions.
* The documentation for identify() incorrectly claimed that the
indices of identified points were returned in the order that the
points were selected. identify() now has a new argument order to
allow the return value to include the order in which points were
identified; the documentation has been updated. Reported by
Richard Rowe and Samuel Granjeaud.
* order(...., decreasing=c(TRUE, FALSE)) could fail in some cases.
Reported from StackOverflow via Karl Nordstr"om.
* User macros in Rd files now accept empty and multi-line
arguments.
* Changes in print.*(), thanks to Lionel Henry's patches in
PR#17398:
* Printing lists, pairlists or attributes containing calls with
S3 class no longer evaluate those.
* Printing S4 objects within lists and pairlists dispatches
with show() rather than print(), as with auto-printing.
* The indexing tags (names or [[<n>]]) of recursive data
structures are now printed correctly in complex cases.
* Arguments supplied to print() are now properly forwarded to
methods when printing lists, pairlists or attributes
containing S3 objects.
* The print parameters are now preserved when printing S3
objects or deparsing symbols and calls. Previously, printing
lists containing S3 objects or expressions would reset these
parameters.
* Printing lists, pairlists or attributes containing functions
now uses srcref attributes if present.
* Calling install.packages() with a length zero pkgs argument now
is a no-op (PR#17422).
* unlist(x) now returns a correct factor when x is a nested list
with factor leaves, fixing PR#12572 and PR#17419.
* The documentation help(family) gives more details about the aic
component, thanks to Ben Bolker's prompting.
* The documentation for attributes and `attributes<-` now gives x
as name of the first and main argument which the implementation
has been requiring, fixing PR#17434. For consistency, the first
argument name is also changed from obj to x for
`mostattributes<-`.
* strwidth() now uses par("font") as default font face (PR#17352).
* plot(<table>, log="x") no longer warns about log.
* The print() method for "htest" objects now formats the test
statistic and parameter directly and hence no longer rounds to
units _before_ the decimal point. Consequently, printing of
t.test() results with a small number of digits now shows
non-large df's to the full precision (PR#17444).
* kruskal.test() and fligner.test() no longer erroneously insist on
numeric g group arguments (PR#16719).
* Printing a news db via the browser now does a much better job
(PR#17433).
* print.aov() missed column names in the multivariate case due to
misspelling (reported by Chris Andrews).
* axis() now creates valid at locations also for small subnormal
number ranges in log scale plots.
* format.POSIXlt() now also recycles the zone and gmtoff list
components to full length when needed, and its internal C code
detects have_zone in more cases. In some cases, this changes its
output to become compatible with format.POSIXct().
* On Windows, detectCores() in package parallel now detects
processors in all processor groups, not just the group R is
running in (impacts particularly systems with more than 64
logical processors). Reported by Arunkumar Srinivasan.
* On Windows, socketSelect() would hang with more than 64 sockets,
and hence parallel::clusterApplyLB() would hang with more than 64
workers. Reported by Arunkumar Srinivasan.
* as(1L, "double") now does coerce (PR#17457).
* lm.influence(), influence.measures(), rstudent() etc now work
(more) correctly for multivariate models ("mlm"), thanks to
(anonymous) stackoverflow remarks.
* sample.int(2.9, *, replace=TRUE) again behaves as documented and
as in R < 3.0.0, namely identically to sample.int(2, ..).
* Fixes to convertColor() for chromatic adaptation; thanks to
Brodie Gaslam PR#17473.
* Using \Sexpr[stage=install]{..} to create an Rd section no longer
gives a warning in R CMD check; problem originally posted by
G'abor Cs'ardi, then reported as PR#17479 with a partial patch by
Duncan Murdoch.
* Parse data now include a special node for equal assignment.
* split.default() no longer relies on [[<-(), so it behaves as
expected when splitting an object by a factor with the empty
string as one of its levels. Thanks to Brad Friedman for the
report.
* Line numbers in messages about .Rd files are now more reliable,
thanks to a patch from Duncan Murdoch.
* In the numeric method for all.equal(), a numeric scale argument
is now checked to be positive and allowed to be of length > 1.
(The latter worked originally and with a warning in recent
years).
* Deferred string conversions now record the OutDec option setting
when not equal to the default. Reported by Michael Sannella.
* When y is numeric and f a factor, plot(y ~ f) nicely uses "y"
and
"f" as y- and x-labels. The more direct boxplot(y ~ f) now does
too. The new argument ann = FALSE may be used to suppress these.
* Subassignment to no/empty rows of a data frame is more consistent
and typically a no-op in all cases instead of sometimes an error;
part of Emil Bode's PR#17483.
* Calls like formatC(*, zero.print = "< 0.001") no longer give
an
error and are further improved via new optional argument
replace.zero. Reported by David Hugh-Jones.
* methods::formalArgs("<fn>") now finds the same function as
formals("<fn>"), fixing Emil Bode's PR#17499.
* The methods package better handles duplicated class names across
packages.
* The default method of seq() now avoids integer overflow, thanks
to the report and "cumsum" patch of Suharto Anggono's
PR#17497.
* sub() no longer loses encodings for non-ASCII replacements
(PR#17509).
* Fix for rotated raster image on X11 device. (Partial fix for
PR#17148; thanks to Mikko Korpela).
* formula(model.frame(frml, ..)) now returns frml in all cases,
thanks to Bill Dunlap. The previous behavior is available as
DF2formula(<model.frame>).
* ar.ols() also returns scalar var.pred in univariate case
(PR#17517).
* normalizePath() now treats NA path as non-existent and normalizes
it to NA. file.access() treats NA file name as non-existent.
file.edit() and connection functions such as file() now treat NA
file names as errors.
* The internal regularize.values() auxiliary of approx(),
splinefun() etc now warns again when there are ties and the
caller did not specify ties. Further, it no longer duplicates x
and y unnecessarily when x is already sorted (PR#17515).
* strtoi("", base) now gives NA on all platforms, following its
documentation. Reported by Michael Chirico.
* In the definition of an S4 class, prototype elements are checked
against the slots of the class, with giving a prototype for an
undefined slot now being an error. (Reported by Bill Dunlap.)
* From setClassUnion(), if environment variable
_R_METHODS_SHOW_CHECKSUBCLASSES is set to true, the internal
.checkSubclasses() utility prints debugging info to see where it
is used.
* max.col(m) with an m of zero columns now returns integer NA
(instead of 1).
* axTicks() no longer returns small "almost zero" numbers (in
exponential format) instead of zero, fixing Ilario Gelmetti's
PR#17534.
* isSymmetric(matrix(0, dimnames=list("A","b"))) is
FALSE again, as
always documented.
* The cairo_pdf graphics device (and other Cairo-based devices) now
clip correctly to the right and bottom border.
There was an off-by-one-pixel bug, reported by Lee Kelvin.
* as.roman(3) <= 2:4 and all other comparisons now work, as do
group "Summary" function calls such as max(as.roman(sample(20)))
and as.roman(NA). (Partly reported by Bill Dunlap in PR#17542.)
* reformulate("x", response = "sin(y)") no longer
produces extra
back quotes, PR#17359, and gains new optional argument env.
* When reading console input from stdin with re-encoding (R
--encoding=enc < input) the code on a Unix-alike now ensures that
each converted input line is terminated with a newline even if
re-encoding fails.
* as.matrix.data.frame() now produces better strings from logicals,
thanks to PR#17548 from Gabe Becker.
* The S4 generic signature of rowSums(), rowMeans(), colSums() and
colMeans() is restricted to "x".
* match(x, tab) now works for long _character_ vectors x, thanks to
PR#17552 by Andreas Kersting.
* Class unions are unloaded when their namespace is unloaded
(PR#17531, adapted from a patch by Brodie Gaslam).
* selectMethod() is robust to ANY-truncation of method signatures
(thanks to Herve Pages for the report).
