[R] Wild cards for dataframes

[Bert Gunter]

A terse but useful resource is to use R's Help docs: ?regex. It also gives
the R regex syntax, which can of course differ from others, especially in
regard to escapes.
Do note that the rseek.org site is a better place to ask for such info than
here. Or just searching on "regular expressions R".
