R for Windows

What's new in this version:

New features:
- iconv() now fixes up variant encoding names such as "utf8" case-insensitively

Deprecated and defunct:
- The legacy encoding = "MacRoman" is deprecated in pdf() and postscript(): support was incomplete in earlier versions of R

Fixed:
- Arguments are now properly forwarded to methods on S4 generics with ... in the middle of their formal arguments. This was broken for the case when a method introduced an argument but did not include ... in its own formals. Thanks to Herv'e Pag`es for the report PR#18538.
- Some invalid file arguments to pictex(), postscript() and xfig() opened a file called NA rather than throw an error. These included postscript(NULL) (which some people expected to work like pdf(NULL)).
- Passing filename = NA to svg(), cairo_pdf(), cairo_ps() or the Cairo-based bitmap devices opened a file called NA: it now throws an error
- quartz(file = NA) opened a file called NA, including when used as a Quartz-based bitmap device. It now gives an error
- rank(<long vector>) now works
- seq.int() did not adequately check its length.out argument
- match(<POSIXct>, .) is correct again for differing time zones, ditto for "POSIXlt"
- drop.terms(*, dropx = <0-length>) now works
- drop.terms(*) keeps + offset(.) terms when it should, PR#18565, and drop.terms() no longer makes up a response, PR#18566, fixing both bugs thanks to Mikael Jagan.
- getS3method("t", "test") no longer finds the t.test() function
- pdf() and postscript() support for the documented Adobe encodings "Greek" and "Cyrilllic" was missing (although the corresponding Windows' codepages could be used).
- Computations of glyph metric information for pdf() and postscript() did not take into account that transliteration could replace one character by two or more (only seen on macOS 14) and typically warned that the information was not known.
- rank(x) no longer overflows during integer addition, when computing rank average for largish but not-yet long vector x
- list.files() on Windows now returns also files with names longer that 260 bytes (the Windows limit is 260 characters). Previously, some file names particularly with 'East Asian' characters were omitted.
- cov2cor(<0 x 0>) now works
- cov2cor(<negative diagonal>) and similar now give one warning instead of two, with better wording
- tools:: startDynamicHelp() now ensures port is in proper range
- pbeta(x, a,b) is correct now for x=0 or 1 in the boundary cases where a or b or both are 0
- pmatch(x, table) for large table, also called for data frame rowselection, dfrm[nm, ], is now interruptible
- predict(<rank-deficient lm>, newdata=*) fix computing of nbasis, see Russ Lenth's comment 29 in PR#16158.
- Added a work-around for a bug in macOS 14.3.1 and higher which prevents R plots in the Quartz Cocoa device from updating on screen
