Hello,
I must be blind not to see it, but I have the following vector:
4
4

6

What I would like to have as a result is:
4
5
6
4
?diff

[1] 4 5 6 4
All repeated values are gone. I cannot use unique for this, as the
second 4
would disappear. Is there another fast function for this problem?
Thanks in advance!
