[Rd] Two ideas / feature requests for R CMD check

[Gábor Csárdi]

We all love R CMD check. :) In my opinion it would be even better if
it had options to

- Run all checks, even if one fails with an error. I realize this
sometimes might not make sense (e.g. if there is no DESCRIPTION file),
but often does.

- Run all examples even if an example fails. I think it would be great
to get all failing examples at once, so that a package author can
estimate the amount of breakage.

Thank you for considering there,
Gabor
