Dear list! > gregexpr("a+(b+)", "abcdaabbc") [[1]] [1] 1 5 attr(,"match.length") [1] 2 4
What I want is the offsets of the matches for the group (b+), i.e. 2 and 7, not the offsets of the complete matches. Is there a way in R to get that? I know about gsubgn and strapply, but they only give me the strings matched by groups not their offsets. I could write something myself that first takes the above matches ("ab" and "aabb") and then searches again using only the group (b+). For this to work, I'd have to parse the regular expression and search several times (> 2, for nested groups) instead of just once. But I'm sure there is a better way to do this. Thanks for any suggestion!
