This blog is updated daily.
A general description is here.
The DVI/PDF reference manual now includes the help pages for all the standard packages: ‘splines’, ‘stats4’ and ‘tcltk’ were previously omitted (intentionally).
‘R CMD check’ has more protection against (probably erroneous) example or test output which is invalid in the current locale.
‘cmdscale(eig = TRUE)’ was documented to return n-1 eigenvalues but in fact only returned ‘k’. It now returns all n eigenvalues.
‘cmdscale(add = TRUE)’ failed to centre the return configuration and sometimes lost the labels on the points. Its return value was described wrongly (it is always a list and contains component ‘ac’).
Backreferences to undefined patterns in ‘[g]sub(pcre = TRUE)’ could cause a segfault. (PR#14431)
The initialization of objects from S4 subclasses of ‘"environment"’ now allocates a new environment object.
