Apologies for the naieveness of this question, but I'm having trouble figuring out to have factor() maintain original ordering.

For example,

foo <- c("b","b","a","a")
levels(factor(foo, ordered=T)) #I'd like this to return as "b" "a"

                                          #not "a" "b"

I thought having ordered=T would do the trick.

Thanks,
Andrew
