This blog is updated daily.
A general description is here.
‘psigamma(x, deriv)’ for negative ‘x’ now also works for ‘deriv = 4’ and ‘5’; their underlying C level ‘dpsifn()’ is documented in ‘Writing R Extensions’.
‘mean()’, ‘rank()’, ‘which()’, ‘barplot()’, ‘boxplot()’, ‘contour()’, ‘polygon()’ and ‘methods::is()’ have more robust sanity checks on some of their arguments.
As does ‘R CMD Rd2pdf’ (used by ‘R CMD check’).
‘hist(<Date>, breaks = "days")’ and ‘hist(<POSIXt>, breaks = "secs")’ no longer fail for inputs of length 1.
‘reformulate(*, response=r)’ gives a helpful error message now when ‘length(r) > 1’, thanks to Bill Dunlap's PR#18281.
Modifying ‘globalCallingHandlers’ inside ‘withCallingHandlers()’ now works or fails correctly, thanks to Henrik Bengtsson's PR#18257.
