R 3.2.4 (codename “Very Secure Dishes”) was released today. You can get the latest binaries version from here. (or the .tar.gz source code from here). The full list of new features and bug fixes is provided below.

Upgrading to R 3.2.4 on Windows

If you are using Windows you can easily upgrade to the latest version of R using the installr package. Simply run the following code in Rgui:

install.packages("installr") # install 
setInternet2(TRUE)
installr::updateR() # updating R.

Running “updateR()” will detect if there is a new R version available, and if so it will download+install it (etc.). There is also a step by step tutorial (with screenshots) on how to upgrade R on Windows, using the installr package.

I try to keep the installr package updated and useful, so if you have any suggestions or remarks on the package – you are invited to open an issue in the github page.

NEW FEATURES

  • install.packages() and related functions now give a more informative warning when an attempt is made to install a base package.
  • summary(x) now prints with less rounding when x contains infinite values. (Request of PR#16620.)
  • provideDimnames() gets an optional unique argument.
  • shQuote() gains type = "cmd2" for quoting in cmd.exe in Windows. (Response to PR#16636.)
  • The data.frame method of rbind() gains an optional argument stringsAsFactors (instead of only depending on getOption("stringsAsFactors")).
  • smooth(x, *) now also works for long vectors.
  • tools::texi2dvi() has a workaround for problems with the texi2dvi script supplied by texinfo 6.1.

    It extracts more error messages from the LaTeX logs when in emulation mode.

UTILITIES

  • R CMD check will leave a log file ‘build_vignettes.log’ from the re-building of vignettes in the ‘.Rcheck’ directory if there is a problem, and always if environment variable_R_CHECK_ALWAYS_LOG_VIGNETTE_OUTPUT_ is set to a true value.

DEPRECATED AND DEFUNCT

  • Use of SUPPORT_OPENMP from header ‘Rconfig.h’ is deprecated in favour of the standard OpenMP define _OPENMP.

    (This has been the recommendation in the manual for a while now.)

  • The make macro AWK which is long unused by R itself but recorded in file ‘etc/Makeconf’ is deprecated and will be removed in R 3.3.0.
  • The C header file ‘S.h’ is no longer documented: its use should be replaced by ‘R.h’.

BUG FIXES

  • kmeans(x, centers = <1-row>) now works. (PR#16623)
  • Vectorize() now checks for clashes in argument names. (PR#16577)
  • file.copy(overwrite = FALSE) would signal a successful copy when none had taken place. (PR#16576)
  • ngettext() now uses the same default domain as gettext(). (PR#14605)
  • array(.., dimnames = *) now warns about non-list dimnames and, from R 3.3.0, will signal the same error for invalid dimnames as matrix() has always done.
  • addmargins() now adds dimnames for the extended margins in all cases, as always documented.
  • heatmap() evaluated its add.expr argument in the wrong environment. (PR#16583)
  • require() etc now give the correct entry of lib.loc in the warning about an old version of a package masking a newer required one.
  • The internal deparser did not add parentheses when necessary, e.g. before [] or [[]]. (Reported by Lukas Stadler; additional fixes included as well).
  • as.data.frame.vector(*, row.names=*) no longer produces ‘corrupted’ data frames from row names of incorrect length, but rather warns about them. This will become an error.
  • url connections with method = "libcurl" are destroyed properly. (PR#16681)
  • withCallingHandler() now (again) handles warnings even during S4 generic’s argument evaluation. (PR#16111)
  • deparse(..., control = "quoteExpressions") incorrectly quoted empty expressions. (PR#16686)
  • format()ting datetime objects ("POSIX[cl]?t") could segfault or recycle wrongly. (PR#16685)
  • plot.ts(<matrix>, las = 1) now does use las.
  • saveRDS(*, compress = "gzip") now works as documented. (PR#16653)
  • (Windows only) The Rgui front end did not always initialize the console properly, and could cause R to crash. (PR#16998)
  • dummy.coef.lm() now works in more cases, thanks to a proposal by Werner Stahel (PR#16665). In addition, it now works for multivariate linear models ("mlm", manova) thanks to a proposal by Daniel Wollschlaeger.
  • The as.hclust() method for "dendrogram"s failed often when there were ties in the heights.
  • reorder() and midcache.dendrogram() now are non-recursive and hence applicable to somewhat deeply nested dendrograms, thanks to a proposal by Suharto Anggono in PR#16424.
  • cor.test() now calculates very small p values more accurately (affecting the result only in extreme not statistically relevant cases). (PR#16704)
  • smooth(*, do.ends=TRUE) did not always work correctly in R versions between 3.0.0 and 3.2.3.
  • pretty(D) for date-time objects D now also works well if range(D) is (much) smaller than a second. In the case of only one unique value in D, the pretty range now is more symmetric around that value than previously.
    Similarly, pretty(dt) no longer returns a length 5 vector with duplicated entries for Date objects dt which span only a few days.
  • The figures in help pages such as ?points were accidentally damaged, and did not appear in R 3.2.3. (PR#16708)
  • available.packages() sometimes deleted the wrong file when cleaning up temporary files. (PR#16712)
  • The X11() device sometimes froze on Red Hat Enterprise Linux 6. It now waits for MapNotify events instead of Expose events, thanks to Siteshwar Vashisht. (PR#16497)
  • [dpqr]nbinom(*, size=Inf, mu=.) now works as limit case, for ‘dpq’ as the Poisson. (PR#16727)
    pnbinom() no longer loops infinitely in border cases.
  • approxfun(*, method="constant") and hence ecdf() which calls the former now correctly “predict” NaN values as NaN.
  • summary.data.frame() now displays NAs in Date columns in all cases. (PR#16709)
