Partial sort?

This is definitely a newbie question but from the documentation I have not been able to figure out what the partial sort option on the sort method does. I have read and re-read the documentation and looked at the examples but for some reason it doesn't register. Would someone attempt to explain what sort with a non-null partial array of indices does?
It guarantees that those particular indices are sorted correctly, but doesn't guarantee anything else. For example, > x <- 10:1 > sort(x, partial=1) guarantees that the first entry in x (i.e. 10) is placed correctly, but nothing else, and the result is: [1] 1 9 8 7 6 5 4 3 2 10 Duncan Murdoch
