This blog is updated daily.
A general description is here.
‘findInterval()’ gets new options ‘checkSorted’ and ‘checkNA’ which allow to skip relatively costly checks; related to PR#16567.
The legecy definition of ‘PI’ in ‘R_ext/Constants.h’ (included by
‘R.h’) will be removeed shortly: use ‘M_PI’ instead.
It is intended that ‘STRICT_R_HEADERS’ will become the default prior to release. This will remove the legacy definitions of ‘PI’, ‘Calloc’, ‘Realloc’ and ‘Free’: use ‘M_PI’, ‘R_Calloc’, ‘R_Realloc’ or ‘R_Free’ instead.
The set of LAPACK (double and complex) routines in API headers ‘R_ext/Lapack.h’ and ‘R_ext/Applic.h’ has been extended, mostly to routines actually in use from packages.
