Be careful: this may throw funny results for exotic regex, but so far, it seems okay. it also drops the first result which always seems to be a duplicate or whole-string match.
strPaitMatch differs in that there should only be two
pairs of parenthesis, then the first (by default) becomes the name, and the
second the value.
strMultiMatch(pattern, text, dropEmpty = FALSE, ...)strPairMatch(pattern, text, swap = FALSE, dropEmpty = FALSE, ...)
regular expression: if it has bracketed sections, these submatches are returned
is the string to match against. This vector should be the same length as the pattern vector, or the patern vector should be length one.
logical whether to drop rows with no matches
are additional parameters passed to regexec and regmatches. I haven't tried this: it may need two separate variables containing lists of params, since this will send everything to both functions.
logical scalar, whether to swap the names and values. Default is not to swap, so the first match becomes the name.
list of character vectors, list length being the length of the inptu text vector.
