Hi,
I am looking for a way to extract an "interesting" part of the match to
a regular expression. For example the pattern "[./](*.)" matches a
substring that begins with either "." or "/" followed by anything. I am
interested in this "anything" w/o the "." or "/" prefix. If say I match
the pattern against "abc/foo" I want to get "foo", not "/foo". In Perl
one can simply wrap the "interesting" part in () and get it out of the
match. Is it possible to do a similar thing in R?
There seems to be a way to refer to the match, see below, but I couldn't
figure out how to make gsub return it.
> gsub("[./](*.)", "\\1", "abc/foo")
[1] "abcfoo"
Thanks,
Vadim
