[R] finding out if a method exists

I'm thinking of adding a new "cmatrix" function/method to the
survival package but before
I do I'd like to find out if any other packages already use this function
name.   The
obvious method is to look at the NAMESPACE file for each package in CRAN and
read the
export list.

This is the kind of task for which someone, somewhere will have written
routines.  I just
don't know who or where.

Any hints?
