| R for Windows 4.5.3 Mar 12, 2026 |
UTILITIES: tools/fetch-recommended can be used instead of tools/rsync-recommended to fetch recommended packages into R sources using curl on systems without rsync or behind firewalls. PACKAGE INSTALLATION: C++ standard specifications (CXX_STD = in src/Makevars* and in the SystemRequirements field of the DESCRIPTION file) are now checked more thoroughly. Invalid values are still ignored but now give a warning, as do contradictory specifications. Preliminary) support for C++26 has been extended to Windows. A non-zero exit status from cleanup, cleanup.win or cleanup.ucrt, if requested via options --clean or --preclean, is now reported with a warning. BUG FIXES: all.equal(obj, simple, check.class=FALSE) now is true, also when simple is a bare atomic vector and obj has a simple class, fixing the first part of PR#18971 thanks to Jan Gorecki. str(x, give.attr=FALSE) no longer shows attributes when x is a zero length "Date" or "POSIXt" object. Tweaks to binning for bw.SJ() and bw.ucv() in the very rare case of data which have an extremely small range compared to their absolute values, e.g., x <- 6e9 + 6:9. Formatting book-type bibentry objects now converts LaTeX accents also in the publisher and series fields. model.frame(~1, list(), na.action=na.pass) and similar border-line uses no longer produce invalid data frames, fixing PR#18977, reported with patch by Mikael Jagan. • length(<POSIXlt>) <- v is more careful about balancing, notably when v is not integer, thanks to Suharto Anggono's remarks on the mailing list R-devel. approx(<x_with_ties>, <y_with_NA>, na.rm = FALSE) now should always call the ties() function, fixing PR#17604 reported by Bill Dunlap. besselJ(1, 1e-15) and similar now give correct results, thanks to Leo Mada and other helpers. vignette(<pkg>::<topic>) is now a documented usage variant and confines vignette retrieval to the specified package. ¢ pretty(ch) again correctly works with ch a char |

• R CMD check now handles archives with extension .tar or .tar.zstd (where zstd compression is supported by the R build). BUG FIXES: t.test(c(1:3, Inf)) and similar no longer produce an error but return a (still not so useful) "htest" result, fixing PR#18901, thanks to Jesse Alderliesten. attr(., "tsp") <- val now uses getOption("ts.eps") instead of hardwired 1e-5; consequently, ts(.., ts.eps=*) now passes ts.eps to the "tsp" setting C code; both fixing a long-standing FIXME™. insertSource() now ignores the internal .packageName object, avoiding a superfluous message. In static HTML help, links to vignette files from the default doc/index.html page now also work for packages not installed in the default .Library, thanks to a report by Patrice Kiener. fixInNamespace("<S3method>") failed to update the S3 methods table when the generic was not on the search path. In plain-text help (Rd2txt), an initial newline from an Rd inline eqn no longer breaks the paragraph. hist(*, log = "x") now works without a warning, thanks to Martin Smith's PR#18921. Subassigning "POSIXlt", i.e., <tdat>[i] <- val and <tdat>[[i]] <- val now rebalance as they should, thanks to Mikael Jagan's PR#18919. <POSIXlt>[*] (re-)setting "balanced", fixing PR#18681 comment #7, thanks to Mikael Jagan. All four of {col,row}{Sums,Means}(Z, na.rm=TRUE) now correctly work with complex Z where is.na(Re(Z)) differs from is.na(Im(Z)), fixing PR#18942, unearthed by Dirk Eddelbuettel. Fix for glyph rendering on the quartz() device when there is other (normal) text drawn on the device. The problem was that the text transformation matrix was not reset so glyphs would be rendered incorrectly (often completely outside the device, i.e., not visible). Functions install.packages() and download.packages() again consult option download.file.method when the download method is unspecified. Tanguy Barthel |

NEW FEATURES: The internal method of unzip() now follows unzip 6.00 in how it handles extracted file paths which contain "../". With thanks to Ivan Krylov. INSTALLATION: Standalone nmath can be built with early-2025 versions of clang-based compilers such as LLVM clang 20, Apple clang 17 and Intel icx 2025.0. Tcl/Tk 9 can be used to build package tcltk: this has become the default in some Linux distributions. *N.B.* several third-party packages currently require Tcl/Tk 8 or even 8.6 without declaring so. BUG FIXES: Java detection in javareconf could not detect libjvm.* in the zero variant of the JDK (PR#18884). All valid variants as of JDK 24u are now supported. factanal(.., rotation=*) now correctly updates rotmat, fixing PR#18886. dnbinom(<large>, <muchlarger>, ..) now is 0 correctly, instead of NaN or Inf sometimes. dbinom(<large>, n=Inf, ..) is 0 now correctly, instead of NaN which also fixes many dnbinom() cases, notably those mentioned in PR#16727 comment #5. Fixing C level “binomial deviance†bd0() for extreme arguments preventing under-/overflow) solves more PR#16727 cases and also prevents some full accuracy loss in such cases for dbinom(), dnbinom(), and via dbinom_raw() potentially dgeom(), dhyper(), dbeta(), and df(). signif(1.**e308, digits) no longer truncates unnecessarily (but still to prevent overflow to Inf), fixing PR#18889. prettyNum(*, zero.print={>=1-char}, replace.zero=TRUE) now works as documented, thanks to Marttila Mikko and Ivan Krylov's messages on R-devel. pbeta(x, a,b, ..) for very large a,b no longer returns NaN but the correct values (0 or 1, or their logs for log.p = TRUE). This improves Mathlib's C level bratio() and hence also pnbinom(), etc.. |
