Partial sort?
I had a similar misunderstanding of using partial in sort() a while back when I was trying to sort by columns, a la Excel. In this case, I ended up using the order() function, eg: require(stats) swiss[order(rownames(swiss)), ] #sort by location swiss[order(swiss$fertility), ] #sort by fertility Not sure if this helps, as I am attempting to do a mind read based on ASCII (I get better results using unicode) Regards, Andrew

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
