This blog is updated daily.
A general description is here.
‘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.
‘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.
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’.
‘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’.
