[R] Loading a rda file for predicton

[TJUN KIAT TEO]

I tried this

--------------------------------------------------------------------------------------------
fit<-glm(Pred~Pressure+MissingStep, data = Test, family="binomial")

save(fit,file="pred.rda")

pred<-load("pred.rda")


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

------------------------------------------------------------------------------------

But got this error message

no applicable method for 'predict' applied to an object of class "character"

What did I do wrong?

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).
