In itree: Tools for classification and regression trees, with an emphasis on interpretability.

Description

Internal functions, only used by packages rpart and ipred.

Usage

pred.rpart(fit, x) 
itree.anova(y, offset, parms, wt)
itree.class(y, offset, parms, wt)
itree.matrix(frame)
itree.class_purity(y, offset, parms, wt)
itree.class_extremes(y, offset, parms, wt)
itree.regression_purity(y, offset, parms, wt)
itree.regression_extremes(y, offset, parms, wt)

Arguments

fit	a tree fitted by itree.
x	a matrix of predictors.
y	the responses.
offset	an offset, or NULL.
parms	a list of parameters, usually empty.
wt	case weights.
frame	model frame (from call to itree)

Value

itree.anova, itree.class, itree.exp, itree.class_purity,itree.class_extremes, itree.regression_purity, itree.regression_extremes, itree.poisson return a list with components

y	(adjusting for offset if necessary),
parms	as input,
numresp	the number of responses,
summary	a function to be invoked by summary.itree,
