Hello,
Maybe this function.
fun <- function(x) x %in% x[duplicated(x)]
x <- c(1, 2, 3, 3)
fun(x)
Hope this helps,

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.
