Betreff: [R] help with repeated values

I have a huge college dataset and I want to be able to find which colleges
appear more than once in the dataset. How would I go about doing this? The
variable college is a factor. If I just do table(college) it is impossible
to find where there are repetitions. Any help would be greatly appreciated!
