[R] regular expression submatch?

[sjaffe]

Thanks for the suggestions.

gsub("hello (.*)", "\\1", "hello world") 

seems simplest. 

Setting value=TRUE returns the whole match, not the subexpression.

(I always read the man pages carefully before asking for help, gratuituous
comments notwithstanding. I didn't see a solution using gregexpr; if the
poster wants to point out my oversight, he is welcome to do so.)
