[R-pkg-devel] R CMD check "no-nanny" option?

To further expand on what has been said before with my own experiences:

After submitting a package and missing those two NOTES (probably because 
I did not use the latest R-devel) my submission was rejected and I was 
asked to change my DESCRIPTION file.

In other words, packages throwing these NOTEs do not seem to be accepted 
on CRAN any more. You probably have to remove "This package..."

Proof: http://cran.r-project.org/web/packages/MPTinR/
(see archive for versions starting with "This package")
