unique vs duplicate problem
Hello, Maybe this function. fun <- function(x) x %in% x[duplicated(x)] x <- c(1, 2, 3, 3) fun(x) Hope this helps, Rui Barradas Em 09-07-2012 17:42, Nico902 escreveu:
Hi, Let say I have a numeric vector: x <- c(1, 2, 3, 3). I want on one hand numbers which are not duplicated ie "1,2" and duplicated "3". so I did:
duplicated(x)
FALSE FALSE FALSE TRUE
unique(x)
1 2 3 which is not what I want. Is there a function in R to have the following result:
duplicated(x)
FALSE FALSE TRUE TRUE
unique(x)
1 2 I could do it by programming some loops but I reckon somebody programmed a function already. Cheers. -- View this message in context: http://r.789695.n4.nabble.com/unique-vs-duplicate-problem-tp4635868.html Sent from the R help mailing list archive at Nabble.com.
