Hi, I don't really understand how ROCR works. Here's another example with a randomforest model: I have the training dataset(bank_training) and testing dataset(bank_testing) and I ran a randomForest as below:
bankrf<-randomForest(y~., bank_training, mtry=4, ntree=2, keep.forest=TRUE,importance=TRUE) bankrf.pred<-predict(bankrf, bank_testing) library(ROCR) pred<-prediction(bankrf.pred$y, bank_testing$y) Here I get the error that the prediction format is incorrect? Where is the mistake?
