I have to correct myself: The above paragraph may be misleading:
Much, if not all of
and make check-all
have worked well since R version 3.1.0 which had in its NEWS an entry
• More of 'make check' will work if recommended packages are not
installed: but recommended packages remain needed for thorough
checking of an R build.
Further, the 'R-admin' manual (on 'make check-all' etc) contains
| Note that these checks are only run completely
| if the recommended packages are installed.
so their presence is not required but much recommended for
