Feature request: non-dropping regmatches/strextract
if you want "to extract regex matches into a new column in a data.frame"
then there are some package functions which do exactly that. three examples
are namedCapture::df_match_variable, rematch2::bind_re_match, and
tidyr::extract. For a more detailed discussion see my R journal submission
(under review) about regular expression packages,
https://raw.githubusercontent.com/tdhock/namedCapture-article/master/RJwrapper.pdf
Comments/suggestions welcome.
