Partial String Matching
Description
charmatch 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 a C function written by Terry Therneau.
Usage
charmatch(x, table, nomatch = NA)
Arguments
x |
the values to be matched. |
table |
the values to be matched against. |
nomatch |
the value returned at non-matching positions. |
