I was trying to do something similar for my trainset but without putting it through the predict function. Instead taking directly from the randomForest which I stored in FOREST_model. I really need to get to this information to do some comparison of certain cases.
RF_DTL<-cbind(testset,predict(FOREST_model, testset, type="response"))
2. In the RF model in R the predict function has three possible arguments: "response", "vote" or "...
