Details

This function is wrapping the function match allowing to pass a vector from which the found elements should be returned. This is often used in a code lookup situation and might be simpler than using match or merge.

Value

A vector of the same length as x giving the elements in ret at the position in idx of the first match if there is a match, otherwise nomatch.
