Hi,
R>=2.9.0 ships grepl, which lets you do that:
any( grepl( TEXT, OBJECT) )
You can also:
install.packages( "operators" )
require( operators )
OBJECT %~+% TEXT

R2.8.1 in OSX
I often combine two commands as follows:
length(grep(TEXT, OBJECT)) > 0
to see if a particular snippet of text exists within an object.
Is there a single command that would accomplish this?
