R decision tree online course
WebAug 17, 2024 · In machine learning, a decision tree is a type of model that uses a set of predictor variables to build a decision tree that predicts the value of a response variable. The easiest way to plot a decision tree in R is to use the prp () function from the rpart.plot package. The following example shows how to use this function in practice. WebJun 9, 2024 · Fitting First Decision Tree For a first vanilla version of a decision tree, we’ll use the rpart package with default hyperpameters. d.tree = rpart (Survived ~ ., data=train_data, method = 'class') As we are not specifying hyperparameters, we are using rpart’s default values: Our tree can descend until 30 levels — maxdepth = 30 ;
