I have factors with levels ``Unit", "Achieved", and "Scholarship"; I
wish to replace these with
"U", "A", and "S".
So I do
fff <- factor(fff,labels=c("U","A","S"))
This works as long as all of the levels are actually present in the
factor. But if ``Scholarship'' is absent
(as if often is) then I get an error.
I can do a workaround such as
fff <- factor(c("U","A","S")[fff],levels=c("U","A","S"))
but this seems kludgy to me.
Is there a sexier way?
cheers,
Rolf Turner
