residuals.rpart(object, type)
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).
|
vector of residuals of type type from a fitted rpart object.
