Hi For instance, we have separate train and test data files (not want to do k fold), so we will not use the function trainControl? In that case if we have to tune the parameters, do we need to specify search =grid in the train function?
My second question is how we can measure MCC classification measure? Is it same like metric=Roc in the train function?
