[R] reverse order of matrix rows

[Jacob Michaelson]

Thanks to those who provided the one-liner answers!  They worked  
quite well.

I'm quite sure that 95% of the questions posted on this mailing list  
could be answered with a quick..."read the manual, stupid...", but  
I'm very grateful to those who take the time to write one-liners.   I  
know that I have been greatly helped by searching through archived  
questions from other people, which I'm sure to some R gurus must have  
seemed like stupid questions.  But in reality the Mailing List  
archives are an invaluable source of documentation, one that wouldn't  
exist if every question were met with a "go read the manual..."  
response.
