[R] Loading a rda file for predicton

[Peter Langfelder]

see help(load) and pay particular attention to what the function
returns: the names of the loaded objects, not the object(s)
themselves.

You have to use

predict(fit,Testsamp,type="response")

since the load() created a variable 'fit' (same name as the one saved).
