Thanks for everybody's help on this and thanks for your patience with my
original mistake.
FWIW, grep doesn't quite do it because if I put it into an "if" test
if (grep(str1,str3) somethingsomething ) { ... }
and str3 does not contain str1, then R gets upset, won't even evaluate
the "if", and returns an error.
I'll take a look at grepl. Turns out I don't have it because I am
currently running rev. 2.8.1-1. Oh well.
Thanks again.
