unique(c(1:10,1)) gives 1:10 (i.e. unique values), is there any
method to get only 2:10 (i.e. values that are unique) ?
The easiest might be:

[1] 1 2 3 4 5 6 7 8 9 10 1
> Vec[table(Vec) == 1]
[1] 2 3 4 5 6 7 8 9 10
Correction!
That should be:
> which(table(Vec) == 1)
2 3 4 5 6 7 8 9 10
2 3 4 5 6 7 8 9 10
or if you don't want a named vector:
> as.vector(which(table(Vec) == 1))
[1] 2 3 4 5 6 7 8 9 10
My initial solution was incorrect and only worked because of the
ordering of the example vector.
Time for another cup of cawfee...Oy
