This blog is updated daily.
A general description is here.
‘R CMD check’ reports more dubious flags in files ‘src/Makevars[.in]’, including ‘-w’ and ‘-g’.
‘table()’ no longer drops an ‘"NaN"’ factor level, and better obeys ‘exclude = <chr>’, thanks to Suharto Anggono's patch for PR#16936. Also, in the case of ‘exclude = NULL’ and ‘NA’s, these are tabulated correctly (again).
Further, ‘table(1:2, exclude = 1, useNA = "ifany")’ no longer erroneously reports ‘<NA>’ counts.
Additionally, all cases of empty ‘exclude’ are equivalent, and ‘useNA’ is not overwritten when specified (as it was by ‘exclude = NULL’).
‘axis(side, x = D)’ and hence ‘Axis()’ and ‘plot()’ now work correctly for ‘"Date"’ and time objects ‘D’, even when “time goes backward”, e.g., with decreasing ‘xlim’. (Reported by William May).
