This blog is updated daily.
A general description is here.
‘utf8ToInt()’ now checks that its input is valid UTF-8 and returns ‘NA’ if it is not.
‘install.packages()’ now allows ‘type = "both"’ with ‘repos = NULL’ if it can infer the type of file.
‘nchar(x, *)’ and ‘nzchar(x)’ gain a new argument ‘keepNA’ which governs how the result for ‘NA’s in ‘x’ is determined. For the R 3.2.x series, the default remains ‘FALSE’ which is fully back compatible. From R 3.3.0, the default will change to ‘keepNA = NA’ and you are advised to consider this for code portability.
‘news()’ more flexibly extracts dates from package ‘NEWS.Rd’ files.
‘lengths(x)’ now also works (trivially) for atomic ‘x’ and hence can be used more generally as an efficient replacement of ‘sapply(x, length)’ and similar.
The included version of PCRE has been updated to 8.37, a bug-fix release.
‘diag()’ no longer duplicates a matrix when extracting its diagonal.
‘as.character.srcref()’ gains an argument to allow characters corresponding to a range of source references to be extracted.
‘acf()’ and ‘ccf()’ now guarantee values strictly in [-1,1] (instead of sometimes very slightly outside). PR#15832.
‘as.integer("111111111111")’ now gives NA (with a warning) as it does for the corresponding numeric or negative number coercions. Further, ‘as.integer(M + 0.1)’ now gives ‘M’ (instead of NA) when M is the maximal representable integer.
On some platforms ‘nchar(x, "c")’ and ‘nchar(x, "w")’ would return values (possibly ‘NA’) for inputs which were declared to be UTF-8 but were not, or for invalid strings without a marked encoding in a multi-byte locale, rather than give an error. Additional checks have been added to mitigate this.
‘apply(a, M, function(u) c(X = ., Y = .))’ again has dimnames containing "X" and "Y" (as in R < 3.2.0).
(Windows only) In some cases, the ‘--clean’ option to ‘R CMD INSTALL’ could fail. (PR#16178)
(Windows only) ‘choose.files()’ would occasionally include characters from the result of an earlier call in the result of a later one. (PR#16270)
A change in ‘RSiteSearch()’ in R 3.2.0 caused it to submit invalid URLs. (PR#16329)
‘Rscript’ and command line ‘R’ silently ignored incomplete statements at the end of a script; now they are reported as parse errors. (PR#16350)
Parse data for very long strings was not stored. (PR#16354)
‘plotNode()’, the workhorse of the ‘plot’ method for ‘"dendrogram"’s is no longer recursive, thanks to Suharto Anggono, and hence also works for deeply nested dendrograms. (PR#15215)
The parser could overflow internally when given numbers in scientific format with extremely large exponents. (PR#16358)
If the CRAN mirror was not set, ‘install.packages(type = "both")’ and related functions could repeatedly query the user for it. (Part of PR#16362)
The low-level functions ‘.rowSums()’ etc. did not check the length of their argument, so could segfault. (PR#16367)
The ‘quietly’ argument of ‘library()’ is now correctly propagated from ‘.getRequiredPackages2()’.
Under some circumstances using the internal PCRE when building R from source would cause external libs such as ‘-llzma’ to be omitted from the main link.
The .Primitive default methods of the logic operators, i.e., ‘!’, ‘&’ and ‘|’, now give correct error messages when appropriate, e.g., for ‘`&`(TRUE)’ or ‘`!`()’. (PR#16385)
‘cummax(x)’ now correctly propagates ‘NA’s also when ‘x’ is of type ‘integer’ and begins with an ‘NA’.
‘summaryRprof()’ could fail when the profile contained only two records. (PR#16395)
HTML vignettes opened using ‘vignette()’ did not support links into the rest of the HTML help system. (Links worked properly when the vignette was opened using ‘browseVignettes()’ or from within the help system.)
‘arima(*, xreg = .)’ (for d >= 1) computes estimated variances based on a the number of effective observations as in R version 3.0.1 and earlier. (PR#16278)
‘slotNames(.)’ is now correct for ‘"signature"’ objects (mostly used internally in ‘methods’).
On some systems, the first string comparison after a locale change would result in ‘NA’.
