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.
