I agree that this would be a useful option sometimes.

So I would be supportive to get such an option, say,

   R CMD check --no-stop-on-error  <pkg>

into R if someone provided (relatively small) patches to the R
sources (i.e. subversion repos at https://svn.r-project.org/R/trunk/ ).
The relevant source code should basically all be in

Note that this may be complicated, also because "parallel"
checking is available in parts, via the TEST_MC_CORES
environment variable ((which is currently only quickly
documented in the 'R Administration ..' manual))
