In order to grow our decision tree, we have to first load the rpart package. Then we can use therpart()function, specifying the model formula, data, and method parameters. In this case, we want to classify the featureFraudusing the predictorRearEnd, so our call torpart()should look l...

The rxDTree function in RevoScaleR fits tree-based models using a binning-based recursive partitioning algorithm. The resulting model is similar to that produced by the recommended R package rpart. Both classification-type trees and regression-type trees are supported; as with rpart, the difference...
