R project testers - how to help out

I just want to find out how I could help out with testing on the R  
project.  I have
many years of software development as well as QA and test of  
everything from
chips to supercomputers and really enjoy testing.  Increasingly, I am  
working in
data mining and large-scale statistical kinds of things and "R" is my  
tool of choice.

Any help is much appreciated.
