Download R 4.1.2

R is a development environment and programming language for statistical and data analysis purposes. It was originally designed by Ross Ihaka and Robert Gentleman (hence the name R) at the University of Auckland, New Zealand. Programming in R is strongly object-oriented and the functionality can be extended via packages that are made available via cran, among others. The R-core team, which is currently involved in the further development, has released version 4.1.2 with the title Bird Hippie. The changes in this release are as follows:

C-Level facilities:

• The workaround in headers Rh and Rmath.h (using namespace std;) for the Oracle Developer Studio compiler is no longer needed now C++11 is required so has been removed. A couple more usages of log() (which should have been std::log()) with an int argument are reported on Solaris.
• The undocumented limit of 4095 bytes on messages from the S-compatibility macros PROBLEM and MESSAGE is now documented and longer messages will be silently truncated rather than potentially causing segfaults.
• If the R_NO_SEGV_HANDLER environment variable is non-empty, the signal handler for SEGV/ILL/BUS signals (which offers recovery user interface) is not set. This allows more reliable debugging of crashes that involve the console.

Deprecated and defunct:

• The legacy S-compatibility macros PROBLEM, MESSAGE, ERROR, WARN, WARNING, RECOVER, … are deprecated and will be hidden in R 4.2.0. R’s native interface of Rf_error and Rf_warning has long been preferred.

Bug fixes:

• .mapply(F, dots, .) no longer segfaults when dots is not a list and uses match.fun(F) as always documented; reported by Andrew Simmons in PR#18164.
• hist(, …) and hist(, …) no longer pass arguments for rect() (such as col and density) to axis(). (Thanks to Sebastian Meyer’s PR#18171.)
• \Sexpr{ch} now preserves Encoding(ch). (Thanks to report and patch by Jeroen Ooms in PR#18152.)
• Setting the RNG to “Marsaglia-Multicarry” eg, by RNGkind(), now warns in more places, thanks to Andr’e Gillibert’s report and patch in PR#18168.
• gray(numeric(), alpha=1/2) no longer segfaults, fixing PR#18183, reported by Till Krenz.
• Fixed dnbinom(x, size=, .., log=TRUE) regression, reported by Martin Morgan.
• as.Date.POSIXlt(x) now keeps names(x), thanks to Davis Vaughan’s report and patch in PR#18188.
• model.response() now strips an “AsIs” class typically, thanks to Duncan Murdoch’s report and other discussants in PR#18190.
• try() is considerably faster in case of an error and long call, as eg, from some do.call(). Thanks to Alexander Kaever’s suggestion posted to R-devel.
• qqline(y =) such as y=I(.), now works, see also PR#18190.
• Non-integer mgp par() settings are now handled correctly in axis() and mtext(), thanks to Mikael Jagan and Duncan Murdoch’s report and suggestion in PR#18194.
• formatC(x) returns length zero character() now, rather than “” when x is of length zero, as documented, thanks to Davis Vaughan’s post to R-devel.
• removeSource(fn) now retains (other) attributes(fn).
