Hello,
Try
i <- !(duplicated(Dup) | duplicated(Dup, fromLast = TRUE))
Dup[i]
or in one line, I post it like this to make it more clear.
Hope this helps,
Rui Barradas

It should be simple but i do not find the right keywords:
Dup = c(1,2,3,4,1,2,3,5)
I need 4,5 as result
unique(Dup) gives me [1] 4 1 2 3 5
duplicated(Dup) gives me
[1] FALSE FALSE FALSE FALSE TRUE TRUE TRUE FALSE
I need
[1] TRUE TRUE TRUE FALSE TRUE TRUE TRUE FALSE
Kind regards Knut
