This blog is updated daily.
A general description is here.
Linear multivariate empty models such as ‘lm(y ~ 0)’ now have a correctly dimensioned empty coefficient matrix; reported by Brett Presnell.
‘vcov(<empty mlm>)’ and hence ‘confint()’ now work (via a consistency change in ‘summary.lm()’).
‘confint(<multivariate lm()>)’ now works correctly; reported on R-devel by Steven Pav.
‘quade.test()’ now also works correctly when its arguments are not yet sorted along ‘groups’, fixing PR#15842.
Installation on a Unix-alike tries harder to link to the ‘pthread’ library where required (rather than relying on OpenMP to provide it: configuring with ‘--disable-openmp’ was failing on some Linux systems).
The ‘data.frame’ method for ‘print(x)’ is fast now also for large data frames ‘x’ and got an optional argument ‘max’, thanks to suggestions by Juan Telleria.
‘hist()’ no longer integer overflows in very rare cases, fixing PR#17450.
‘untar()’ ignored a character ‘compressed’ argument: however many external ‘tar’ programs ignore the flags which should have been set and automagically choose the compression type, and if appropriate ‘gzip’ or ‘bzip2’ compression would have been chosen from the magic header of the tarball.
‘zapsmall(x)’ now works for more “number-like” objects.
The tools-internal function called from ‘R CMD INSTALL’ now gets a ‘warnOption = 1’ argument and only sets ‘options(warn = warnOption)’ when that increases the warning level (PR#17453).
