A general description is here.
‘R CMD check’ now reports empty ‘importFrom’ declarations in a ‘NAMESPACE’ file, as these are common errors (writing ‘importFrom(Pkg)’ where ‘import(Pkg)’ was intended).
There is support for testing the ‘\dontrun’ and ‘\donttest’ parts of examples in packages.
‘tools::testInstalledPackage()’ accepts new arguments ‘commentDontrun = FALSE’ and ‘commentDonttest = FALSE’.
‘R CMD check’ gains ‘--run-dontrun’ and ‘--run-donttest’ options.
