Hi Megh, You're right. It happens because the replications of some elements of your vector x are "removed" once you put the condition. So, when you type table(x) and table(x1), you'll have something like this:
# x # 68 72 80 84 88 92 96 100 # 2 2 1 2 5 2 3 3 # x1 # 88 92 96 # 2 2 1 length(x) is 20 and length(x1) is 5, but when you type x[!x%in%x1] you're removing the elements of x that are present in x1, *including* replications. I just read Peter Dalgaard's reply while I was writing this email. If you are interested in "what "remains" when you remove a value that occurs multiple times in x", as he said, just follow his advice.
