[R] find duplicates... need help!

Hi all, Suppose I have x = c('a', 't', 'c', 'y', 'g') and also y = c('a', 'a', 'g', 's') If I do something like x%in%y, I obtain a vector like this: [TRUE, FALSE, FALSE, FALSE, TRUE] which I can easily turn into this: [1, 0, 0, 0, 1]. I was wondering is there anyway for me to get a vector back

Dear njhuang86, Here is one way: x - c('a', 't', 'c', 'y', 'g') y - c('a', 'a', 'g', 's') table(factor(y, levels = x)) # a t c y g # 2 0 0 0 1 HTH, Jorge On Tue, Jul 7, 2009 at 3:28 PM, njhuang86 njhuan...@yahoo.com wrote: Hi all, Suppose I have x = c('a', 't', 'c', 'y', 'g') and also y
