[R] grep fixed (?) in 2.14

[Stephen Sefick]

#This is probably due to my incomplete understanding of grep, but the 
below code has been working for some time to
#search for .R with anything in front of it and return a list of scripts 
to source.  Likely, the syntax for the
#grep statement has been wrong all along.
