R Project Updates

Updates from R Core:

  • R CMD check --as-cran now NOTEs if the package does not register its native routines or does not declare its intentions on (native) symbol search. (This will become a WARNING in due course.)

  • Those who use proxies should check that their settings are compatible (see ?download.file: the most commonly used forms work for both methods "internal" and "libcurl").

  • One can now choose from alternative matrix product implementations via options(matprod = ). The "internal" implementation is not optimized for speed but consistent in precision with other summations in R (uses long double accumulators). "blas" calls BLAS directly for best speed, yet usually with undefined behavior for inputs with NaN/Inf.

  • (Unix-alike) The default method for download.file() and url() now always chooses "libcurl" except for file:// URLs. There will be small changes in the format and wording of messages, and those who use proxies should check that their settings are compatible (see ?download.file: the most commonly used forms work for both methods "internal" and "libcurl").

  • Three changes when redirection of a http:// URL to a https:// URL is encountered.

  • (Unix-alike) For http:// URLs and the default method ("auto"), download.file() switches to method = "libcurl" if a redirection to a https:// URL is encountered.

  • For url() with method "default" and an explicit open argument, if opening fails because of redirection to an https:// URL then method = "libcurl" is tried.
