The build system sent R-3.2.1.tar.gz (codename "World-Famous Astronaut") in orbit this morning. The list below details the changes in this release. You can get the source code from http://cran.r-project.org/src/base/R-3/R-3.2.1.tar.gz or wait for it to be mirrored at a CRAN site nearer to you. Binaries for various platforms will appear in due course. For the R Core Team, Peter Dalgaard These are the md5sums for the freshly created files, in case you wish to check that they are uncorrupted: MD5 (AUTHORS) = eb97a5cd38acb1cfc6408988bffef765 MD5 (COPYING) = eb723b61539feef013de476e68b5c50a MD5 (COPYING.LIB) = a6f89e2100d9b6cdffcea4f398e37343 MD5 (FAQ) = 181370b39076e34f64b842257076cd5c MD5 (INSTALL) = 3964b9119adeaab9ceb633773fc94aac MD5 (NEWS) = 6342bc1164e9f8e17713f47cff1910b4 MD5 (NEWS.0) = bfcd7c147251b5474d96848c6f57e5a8 MD5 (NEWS.1) = eb78c4d053ec9c32b815cf0c2ebea801 MD5 (NEWS.2) = 8e2f4d1d5228663ae598a09bf1e2bc6b MD5 (R-latest.tar.gz) = c2aac8b40f84e08e7f8c9068de9239a3 MD5 (README) = aece1dfbd18c1760128c3787f5456af6 MD5 (RESOURCES) = a59076c1ac7e9bab0f0a38b3f57a3914 MD5 (THANKS) = ba00f6cc68a823e1741cfa6011f40ccb MD5 (R-3/R-3.2.1.tar.gz) = c2aac8b40f84e08e7f8c9068de9239a3 This is the relevant part of the NEWS file CHANGES IN R 3.2.1: NEW FEATURES: * 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 NAs 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. BUG FIXES: * 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 fron 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 NAs 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.
