This blog is updated daily.
A general description is here.
The number of items retained with ‘options(warn = 0)’ can be set by ‘options(nwarnings=)’.
The ‘clusterExport’ function now allows specification of an environment from which to export.
‘R CMD INSTALL’ will now do a test load for all sub-architectures for
which code was compiled (rather than just the primary
sub-architecture).
‘R CMD INSTALL’ will test loading under all installed sub-architectures even for packages without compiled code, unless the flag ‘--no-multiarch’ is used. (Pure R packages can do things which are architecture-dependent: in the case which prompted this, looking for an icon in a Windows R executable.)
‘R CMD INSTALL’ will now do a test load for all sub-architectures for which code was compiled (rather than just the primary sub-architecture).
The internal ‘plot.default()’ code did not do sanity checks on ‘cex’, so invalid input could cause problems. (Reported by Ben Bolker.)
‘anyDuplicated(<array>, MARGIN=0)’ no longer fails. (Reported by Hervé Pagès.)
‘options(warn = 0)’ failed to end a (C-level) context with more than 50 accumulated warnings. (Spotted by Jeffery Horner.)
