na.rpart (Package: rpart) :

Handles missing values in an "rpart" object.

● Data Source: CranContrib
● Keywords: tree
● Alias: na.rpart
● 0 images

meanvar.rpart (Package: rpart) :

Creates a plot on the current graphics device of the deviance of the node divided by the number of observations at the node. Also returns the node number.

● Data Source: CranContrib
● Keywords: tree
● Alias: meanvar, meanvar.rpart
● 0 images

post.rpart (Package: rpart) :

Generates a PostScript presentation plot of an rpart object.

● Data Source: CranContrib
● Keywords: tree
● Alias: post, post.rpart
● 0 images

labels.rpart (Package: rpart) :

This function provides labels for the branches of an rpart tree.

● Data Source: CranContrib
● Keywords: tree
● Alias: labels.rpart
● 0 images

prune.rpart (Package: rpart) :

Determines a nested sequence of subtrees of the supplied rpart object by recursively snipping off the least important splits, based on the complexity parameter (cp).

● Data Source: CranContrib
● Keywords: tree
● Alias: prune, prune.rpart
● 0 images

xpred.rpart (Package: rpart) :

Gives the predicted values for an rpart fit, under cross validation, for a set of complexity parameter values.

● Data Source: CranContrib
● Keywords: tree
● Alias: xpred.rpart
● 0 images

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.

● Data Source: CranContrib
● Keywords: tree
● Alias: rsq.rpart
● 0 images

snip.rpart (Package: rpart) :

Creates a "snipped" rpart object, containing the nodes that remain after selected subtrees have been snipped off. The user can snip nodes using the toss argument, or interactively by clicking the mouse button on specified nodes within the graphics window.

● Data Source: CranContrib
● Keywords: tree
● Alias: snip.rpart
● 0 images

summary.rpart (Package: rpart) :

Returns a detailed listing of a fitted rpart object.

● Data Source: CranContrib
● Keywords: tree
● Alias: summary.rpart
● 0 images

rpart.exp (Package: rpart) : Initialization function for exponential fitting

This function does the initialization step for rpart, when the response is a survival object. It rescales the data so as to have an exponential baseline hazard and then uses Poisson methods. This function would rarely if ever be called directly by a user.

● Keywords: tree
● Alias: rpart.exp
