R help - Jun 2012 - Subtracting test string from vectors

Hi all,

let I have two text string:

*one <-
c("ciao","zio","caio","bello")
two <- c("caio","zio")*

I would like to obtain a new text string which is* one - two* like this one:

[1] "ciao" "bello"

because "caio" and "zio" elements have been subtracted from
*one*.

What's the most efficient way to obtain this?

Thank you,

Hope this helps,
