R help - Nov 2003 - Loading file to use with qda()

z <- qda(train, cl)
save(z, file = "qda.dat")
load("qda.dat")
predict(qda.dat, test)$class

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 ...
