thanks everyone.   all solutions were better than what I had, and 

R is an interesting experience.  Extremely powerful and awe-inspiring 
for its elegance;  things work like I would never have believed how 
elegantly  they work.  The IQ in the subsetting alone is superbly 
clever.  And then it turns around: figuring out how to do simple things 
can take a long time---until I realize that it is somewhere somehow 
built in already.  So, R (and the answers from helpful souls on this 
list) often makes me feel quite stupid.  Yes, I first search; yes, I 
always look---but either I did not know or I had forgotten.

I used to use perl for much work, and although there is much to like 
about it, R seems to be even better for most tasks---except that there 
is one perl resource that R cannot beat:  the Perl Cookbook.  if I only 
had an R cookbook...
