Hi,
Try this:
#Duplicated:
x<-c(1:3,3)
x==x[duplicated(x)]
#[1] FALSE FALSE TRUE TRUE
#Unique:
x[!x==x[duplicated(x)]]
#[1] 1 2

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

Here is one way of doing it -- you can create your own functions:

+ function (value)
+ {
+ duplicated(value) | duplicated(value, fromLast = TRUE)
+ }

[1] 3

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:
>dupli
