This blog is updated daily.
A general description is here.
‘tempdir(check = TRUE)’ recreates the ‘tempdir()’ if it is no longer valid (e.g. because some other process has cleaned up the ‘/tmp’ directory).
‘coef()’ methods (for ‘lm’ etc) also gain a ‘complete = TRUE’ optional argument for consistency with ‘vcov()’. For ‘"aov"’, both ‘coef()’ and ‘vcov()’ methods remain back compatibly consistent, using the _other_ default, ‘complete = FALSE’.
The printing of named raw vectors is now formatted nicely as for other such atomic vectors, thanks to Lukas Stadler.
