Details

``find.match'' attempts to use several common matching functions in an order that sequentially prefers less strict matching, until a suitable match is found. If none is found, then return the value of the ``fail'' parameter (defaults to NA). The functions used for matching are: ``match'', ``charmatch'', and finally ``grep''.
