Loading file to use with qda()

I'm trying to save z where z <-qda(train, cl) and load z for later use in predict(z, test)$class.
I think I successfully saved z by save(z, file = "qda.dat") but when I tried to load by load("qda.dat") and
call predict(qda.dat, test)$class, it gives me error 'object qda.dat is not found'.
Does anybody have an idea?
You saved an object called z in a file called qda.dat. After loading the file qda.dat, the object called z is in your workspace, so you can use: predict(z, test)$class Maybe you called z in the former session also qda.dat (like the file), but you saved only the object called z ... Uwe Ligges
