Hi,
I have a randomforest object "cost.rf" that was created in splus 8.0,
now I need to use this trained RF model in R. So in Splus, I dump the RF
file as below
data.dump("cost.rf", file="cost.rf.txt", oldStyle=T)
then in R, restore the dumped file,
library(foreign)
data.restore("cost.rf.txt")
it works fine and able to restore the "cost.rf" object. But when I try
to pass a new data through this randomforest object using predict()
function, it gives me error message.
in R:
library(randomForest)
set.seed(2211)
pred <- predict(cost.rf, InputData[ , ])
Error in object$forest$cutoff : $ operator is invalid for atomic vectors
Looks like after restoring the dump file, the object is not compatible
in R. Have anyone successfully converted a splus randomforest object to
R? what will be the appropriate method to do this?
Thanks in advance.
Jimmy
