Mastering regular expressions by Jeffrey Friedl
(http://books.google.com/books?q=editions%3AISBN0596528124) is the
classic reference.  Although it doesn't cover R explicitly, R does
support perl compatible regular expressions which are discussed in the
book.  Regardless, most of the topics are general enough not to depend
tightly on the specific regexp engine.
