Re: [R] error in random forest

I've had the same problem and solved it by removing the cases with the new levels - they need to be handled some other way, either by building a new model or reassigning the factor level to one in the training set. Nagu wrote: > > Hi, > > I get the following error when I try to predict the pr

[R] error in random forest

Hi, I get the following error when I try to predict the probabilities of a test sample: Error in predict.randomForest(fit.EBA.OM.rf.50, x.OM, type = "prob") : New factor levels not present in the training data I have about 630 predictor variables in the dataset x.OM (25 factor variables and th
