R Project Updates

Updates from R Core,

  • Header Rconfig.h no longer defines SUPPORT_OPENMP; use _OPENMP as long documented.

  • HAVE_UINTPTR_T is now defined where appropriate by Rconfig.h so that it can be included before Rinterface.h when CSTACK_DEFNS is defined and a C compiler (not C++) is in use. Rinterface.h now includes C header stdint.h or C++11 header cstdint where needed.

  • No-longer-installed headers GraphicsBase.h, RGraphics.h, Rmodules/RX11.h and Rmodules/Rlapack.h which had a LGPL license no longer do so.

  • Enviromental variable _R_CHECK_TESTS_NLINES_ controls how R CMD check reports failing tests (see §8 of the R Internals manual).

  • The default method for quantile(x, prob) should now be monotone in prob, even in border cases, see PR#16672.

  • The check for the zlib version is now robust to versions longer than 5 characters, including 1.2.10.

  • seq("2", "5") now works too, equivalently to "2":"5" and seq.int().

  • seq.int(to=1, by=1) is now correct, other cases are integer (instead of double) when seq() is integer too, and the “non-finite” error messages are consistent between seq.default() and seq.int(), no longer mentioning NaN etc.
