pmatch {base} | R Documentation |
pmatch
seeks matches for the elements of its first argument
among those of its second. If there is a unique match then the index
of the matching value is returned; if multiple matches are found then
0
is returned and if no match is found then NA
is
returned.
This function is based on Terry Therneau's charmatch
S function.
In R, charmatch
is synonym to pmatch
