This blog is updated daily.
A general description is here.
‘assertError()’ and ‘assertWarning()’ (in package ‘tools’) can now check for _specific_ error or warning classes _via_ the new optional second argument ‘classes’ (which is not back compatible with previous use of an unnamed second argument.)
‘approxfun()’ and ‘approx()’ gain a new argument ‘na.rm’ defaulting to true. If set to false, missing ‘y’ values now propagate into the interpolated values.
Long vectors are now supported in ‘for()’ loops.
‘rbind.data.frame()’ no longer drops ‘<NA>’ levels from factor columns by default, PR#17562.
The use of a character vector with ‘.Fortran()’ is depreacated and gives a non-portability warning.
‘rbind.data.frame()’ allows to keep ‘<NA>’ levels from factor columns (PR#17562) via new option ‘factor.exclude’.
