[R] sorting without order

In order to increase the performance of a script I'd like to sort very large vectors containing repeated integer values.
I'm not interesting in having the values sorted, but only grouped.
I also need the equivalent of index.return from the standard "sort" function:
is there a way to achieve this which would be faster than the standard sort function?
Thanks for any hints,
