rsq.rpart

Plots the Approximate R-Square for the Different Splits

Description

Produces 2 plots. The first plots the r-square (apparent and apparent - from cross-validation) versus the number of splits. The second plots the Relative Error(cross-validation) +/- 1-SE from cross-validation versus the number of splits.

Usage

rsq.rpart(x)

Arguments

`x`	fitted model object of class `"rpart"`. This is assumed to be the result of some function that produces an object with the same named components as that returned by the `rpart` function.

Side Effects

Two plots are produced.

Note

The labels are only appropriate for the "anova" method.

Examples

z.auto <- rpart(Mileage ~ Weight, car.test.frame)
rsq.rpart(z.auto)
