book on regular expressions

Could someone recommend a good book on regular expressions with focus
on
applications/use as it might relate to R. I remember there was a
mention of
such a reference book recently, but I could not locate that message
on the
archive.
It's not specific to R, which wraps regular expressions up in quoted strings so has a couple of wrinkles compared to Perl, but I found the O'Reilly " Regular Expression Pocket Reference" a good quick reference, and rather cheaper than the whole book. It's hard to see R users needing chapter and verse on the complete gamut of regexps. Steve E
