How to Plot a Decision Tree in R (With Example) - Statology 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.

How to Fit Classification and Regression Trees in R - Statology Step 2: Build the initial regression tree. First, we'll build a large initial regression tree. We can ensure that the tree is large by using a small value for cp, which stands for "complexity parameter.". This means we will perform new splits on the regression tree as long as the overall R-squared of the model increases by at least the ...
