Thank you, Brian.

though that would be less concise and I think less matching the
'R CMD check' philosophy with many '--no-*' options to turn
*off* defaults. Note that most options have no " = <value>" part, because
they are binary and I think that's easiest for use (when the 'binary' case 
is general enough). Also   R CMD check --help      
ends saying  "By default, all test sections are turned on."
which does fit the use of all those '--no-*' options.

OTOH, we also have  '--ignore-vignettes'
so we could consider

   --ignore-tests-errors

?

You are quite right on that, indeed.
