Regexp Match Operator
Description
A grep sub like function that actually returns the n back-referenced *matches*
(as columns in a datframe of the same length as the input vector). This function
is more geared towards *extracting* than cleaning ...
even though it uses sub (a cleaning function) to do so.
Usage
m(pattern, vect, names="V", types="character")

vect |
A string or vector of strings one which to apply the pattern match. |
names |
The vector of names of the new variables to be created out of vect. Must be the same length as vect. |
