[R] grep question

[jim holtman]

This finds the matching indices of Farrah and Common and then create a
set that does not include them:

> x <- c('Farrah', 'more', 'Common', 'last')
> got.F <- grep('Farrah',x)
> got.C <- grep('Common', x)
> not.ForC <- setdiff(seq(along=x), c(got.F, got.C))
> x[not.ForC]
[1] "more" "last"
