You'd get better help if you actually did as Steve requested and provided sample data (a reproducible example!) using dput().
But since you didn't: > fakedata <- data.frame(a = 1:5, b=11:15, c=c(1,1,1,2,2)) > fakedata a b c 1 1 11 1 2 2 12 1 3 3 13 1 4 4 14 2 5 5 15 2 > notb <- c(12, 14, 15) > subset(fakedata, !b %in% notb) a b c 1 1 11 1 3 3 13 1 Since you say that doesn't work for you, you absolutely have to provide us with a reproducible example for anyone to be able to diagnose your problem.
