there seems to be something wrong with r's regexing. consider the following example: gregexpr('a*|b', 'ab') # positions: 1 2 # lengths: 1 1 gsub('a*|b', '.', 'ab') # .. where the pattern matches any number of 'a's or one b, and replaces the match with a dot, globally. the answer is correct (assuming a dfa engine).
