[R] Bug report: override stopifnot() ?

[Stepan Kasal]

Hello,
I stumbled over a problem:
   stopifnot(m1 == m2)

It works with vector or matrix, but does not work for classes from Matrix package.

In the source of stopifnot(), there is all(m1 == m2) that would just work,
but there is also is.logical(m1 == m2) that id FALSE.

Would it be possible if Matrix package redefined stopifnot() ?

(If there is a bug tracking database for package Matrix, I would be happy to insert this report there.)

Thank you very much for the package,
