Re: [R] help with repeated values

Here you have an example: > colleges <- factor( c("a", "a", "b", "c", "c" )) > colleges [1] a a b c c Levels: a b c > table( colleges ) colleges a b c 2 1 2 > colleges.count <- table( colleges )[colleges] > colleges.count colleges a a b c c 2 2 1 2 2 > which( colleges.count > 1 ) a a c c 1 2 4 5
