R Portable Files

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.
