Description

This is intended as a 'drop-in' replacement for grepl and should give identical results This function first matches on the unique strings and then matches back to the original, so it will give a speedup iff length(unique(words)) << length(words)

Usage

Arguments

pattern	a regular expression pattern to use
words	a vector of words, this should probably be a factor to achieve speedup
ignore.case	passed to grepl, defaults to TRUE for this function
