grep fixed (?) in 2.14
That did the trick. I have read about regular expressions often, and sometimes I get them right and sometimes I don't. Is there a good reference resource that anyone could suggest? Thanks for all of the help. Stephen Sefick

your syntax is wrong, you need:
scripts2source[grep("*\\.R$", scripts2source)]
Notice the '\\.' to escape the special meaning of '.', and the "$" to
anchor to the end of the line.
