I don't know.
Hmm. If the origins of the name are lost in the mists of history,
I'm flattered, but I feel obliged to point out that just because I don't know something doesn't mean the information does not exist. Duncan Murdoch
From the SVN log:

add xtfrm, use it in order() etc
make is.unsorted work on classed objects

Adding
xtfrm.numeric <- function(x) {x}
