strMultiMatch

strPairMatch

regular expression: if it has bracketed sections, these
submatches are returned

pattern

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.

text

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 whether to drop rows with no matches

dropEmpty

logical scalar, whether to swap the names and values. Default is
not to swap, so the first match becomes the name.

swap

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<p></p><p><code>strPaitMatch</code> differs in that there should only be two
  pairs of parenthesis, then the first (by default) becomes the name, and the
  second the value.</p>

This package allows accurate manipulation, conversion, validation
    and comparison of ICD-9-CM (clinical modification) codes. Although ICD-9
    codes appear numeric, this is not the case, since trailing zeroes, and a
    mixture of decimal and non-decimal "short" format codes exist. Tools to map
    ICD-9 codes to co-morbidities are also provided, with mappings from Quan
    (Deyo and Elixhauser versions), Elixhauser and AHRQ included.
