CHANGES IN R 4.5.2:

  UTILITIES:

    • R CMD check now handles archives with extension .tar or .tar.zstd
      (where zstd compression is supported by the R build).

  BUG FIXES:

    • t.test(c(1:3, Inf)) and similar no longer produce an error but
      return a (still not so useful) "htest" result, fixing PR#18901,
      thanks to Jesse Alderliesten.

    • attr(., "tsp") <- val now uses getOption("ts.eps") instead of
      hardwired 1e-5; consequently, ts(.., ts.eps=*) now passes ts.eps
      to the "tsp" setting C code; both fixing a long-standing ‘FIXME’.

    • insertSource() now ignores the internal .packageName object,
      avoiding a superfluous message.

    • In static HTML help, links to vignette files from the default
      doc/index.html page now also work for packages not installed in
      the default .Library, thanks to a report by Patrice Kiener.

    • fixInNamespace("<S3method>") failed to update the S3 methods
      table when the generic was not on the search path.

    • In plain-text help (Rd2txt), an initial newline from an Rd inline
      \eqn no longer breaks the paragraph.

    • hist(*, log = "x") now works without a warning, thanks to Martin
      Smith's PR#18921.

    • Subassigning "POSIXlt", i.e., <tdat>[i] <- val and <tdat>[[i]] <-
      val now rebalance as they should, thanks to Mikael Jagan's
      PR#18919.

    • <POSIXlt>[*] (re-)setting "balanced", fixing PR#18681 comment #7,
      thanks to Mikael Jagan.

    • All four of {col,row}{Sums,Means}(Z, na.rm=TRUE) now correctly
      work with complex Z where is.na(Re(Z)) differs from is.na(Im(Z)),
      fixing PR#18942, unearthed by Dirk Eddelbuettel.

    • Fix for glyph rendering on the quartz() device when there is
      other (“normal”) text drawn on the device.  The problem was that
      the text transformation matrix was not reset so glyphs would be
      rendered incorrectly (often completely outside the device, i.e.,
      not visible).

    • Functions install.packages() and download.packages() again
      consult option download.file.method when the download method is
      unspecified.

    • Tanguy Barthelemy and colleagues at the ‘R Dev Day’ following
      Rencontres R in May 2025 extended the help page of lm(), fixing
      PR#18058.  As suggested by Thomas Soeiro, such notes were also
      added to the glm(), poly() and splines::bs() and ns() pages.

    • lbeta(1i, 1) now signals an error, as lbeta() is not implemented
      for complex, fixing PR#18946 from Ben Bolker and Kasper
      Kristensen.

    • The Cairo-based SVG device uses pt as the default document unit
      also with Cairo >= 1.17.8 (PR#18912).

    • pretty(*, eps.correct = 2) has been fixed, e.g., to avoid over 1
      million length result for pretty(c(0, 1e-322), eps.correct = 2).

    • When "POSIXlt" date-time objects are NA-padded from subsetting or
      increasing length in the `[` or `length<-` methods, the
      "balanced" attribute is set to NA, now; noted in PR#18681, thanks
      to Mikael Jagan.
