Residuals From a Fitted Rpart Object

Usage

residuals.rpart(object, type)

Arguments

object 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.
type Indicates method of residual for a classification tree (no distinction is made for methods "anova", "poisson", or "exp"). Allows the following types of residuals: "usual" (misclassification errors), "pearson" (sum of the observed minus fitted squared over fitted), and "deviance" (minus twice logarithm of fitted).

Value

vector of residuals of type type from a fitted rpart object.

Examples

fit <- rpart(skips ~ Opening + Solder + Mask + PadType + Panel,
       data=solder, method='anova')
plot(fitted(fit),residual(fit))
