Details

If an element of patterns contains a comma, then that element is matched against the *getFullNames(), otherwise it is matched against *getNames(). First each pattern is matched by regular expression rules, and if there is not match, then by fixed strings.

Value

Returns an integer vector of length K with elements in [1,*length()] or (integer) NA (for non-matched names).
