Derar R-people

I have troubles understanding what the function sort.list() is doing. On
the homepage it says that it returns a permutation which rearranges a
vector into ascending or descending order (like order() but on a vector
instead of a sequence).

> sort.list(c(0, 2, 10, 11, 4))
[1] 1 2 5 3 4

which does not make sense to me.

In fact I am getting the same (non-sensical) result using order()

order(c(0, 2, 10, 11, 4))
[1] 1 2 5 3 4

Of course

rank(c(0, 2, 10, 11, 4))
1] 1 2 4 5 3

gives the correct result.

Am I missing something obvious here ?

Cheers Ole
