This blog is updated daily.
A general description is here.
‘An Introduction to R’ has a new chapter on using R as a scripting language, interacting with the OS.
Various functions in ‘stats’ and elsewhere that use non-standard evaluation are now more careful to follow the namespace scoping rules. E.g. ‘stats::lm()’ can now find ‘stats::model.frame()’ even if ‘stats’ is not on the search path or if some package defines a function of that name.
If an invalid/corrupt ‘.Random.seed’ object is encountered in the workspace it is ignored with a warning rather than giving an error. (This allows R itself to rely on a working RNG, e.g. to choose a random port.)
The included version of ‘zlib’ has been updated to 1.2.8, a bug-fix release.
There is now support for the LaTeX style file ‘zi4.sty’ which has in some distributions replaced ‘inconsolata.sty’.
The included version of xz utils's ‘liblzma’ has been updated to 5.0.5.
‘stem()’ now discards infinite inputs rather than hanging. (PR#15376)
On systems where ‘mktime()’ does not set ‘errno’, the last second before the epoch could not be converted from ‘POSIXlt’ to ‘POSIXct’. (Reported by Bill Dunlap.)
‘add1.glm()’ miscalculated F-statistics when df > 1. (Bill Dunlap, PR#15386).
