Extracting matched expressions
Hi all,
Is there a tool in base R to extract matched expressions from a
regular expression? i.e. given the regular expression "(.*?) (.*?)
([ehtr]{5})" is there a way to extract the character vector c("one",
"two", "three") from the string "one two three" ?
Thanks,
Hadley
