I think you are looking for the %in% and %nin% which are part of Design package,
and also in Hmisc library. You have t

[1] "a" "b" "c"

Ooops sorry for html tags... Just forgot to edit the message
before sending it...
So back to my question:
Thx for the hint, but what would I have used if "b","c" and "d"
were values of a dataframe for instance?
X is for instance a dataframe:
>X
Mypatterns
1 pattern1
2 pattern2
3 patte
Thx for the hint, but what would I have used if "b","c" and "d"
were values of a dataframe for instance?

Dear R-users,
is there a way to pass a list of patterns to the grep function? I
vaguely remember something with %in% operator...
Thanks,
