R Project Updates

Updates from R Core:

  • bw.SJ() and density(*, bw="SJ") no longer fail because of integer overflow for large sample size n (starting from n as small as 65536).

  • download.file(method="libcurl") does not check for URL existence before attempting downloads; this is more robust to servers that do not support HEAD or range-based retrieval, but may create empty or incomplete files for aborted download requests.

  • Bandwidth selectors bw.ucv() and bw.SJ() gave incorrect answers or incorrectly reported an error (because of integer overflow) for inputs longer than 46341. Similarly for b2.bcv() at length 5793. Another possible integer overflow is checked and may result in a reported error (rather than an incorrect result) for much longer inputs (millions for a smooth distribution).
