This should work unless you use 3 consecutive winking elephants in other places in your program. -----Original Message----- From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On Behalf Of Nipesh Bajaj Sent: Wednesday, February 09, 2011 10:12 AM To: r-help@r-project.org Subject: [R] A question on Duplicating Hello I am struggling to accomplice an idea which is as follows: I have a vector say: a <- c("a", "b", "c", "a") and another: b <- c("m", "n", "o", "m"). Length of those 2 vectors are essentially be same. Here task is to check the duplicates in the vector 'a' and then to check whether any duplicates are there in the same places of 'b'. If not, flag a FALSE. I above example, it is correct hence TRUE. However in general how can I implement this? Can somebody please help me?
