vt.subgroups: Visualize subgroups

In aVirtualTwins: Adaptation of Virtual Twins Method from Jared Foster

Description

Function which uses VT.tree intern functions. Package rpart.plot must be loaded. See VT.tree for details.

Usage

vt.subgroups(vt.trees, only.leaf = T, only.fav = T, tables = F,
  verbose = F, compete = F)

Arguments

vt.trees	VT.tree object. Or return of vt.tree function. Can be a list.
only.leaf	logical to select only leaf of trees. TRUE is default.
only.fav	logical select only favorable subgroups (meaning with favorable label of the tree). TRUE is default.
tables	set to TRUE if tables of incidence must be shown. FALSE is default.
verbose	print infos during computation. FALSE is default.
compete	print competitors rules thanks to competitors computation of the tree

Value

data.frame of rules

Examples

data(sepsis)
vt.o <- vt.data(sepsis, "survival", "THERAPY", TRUE)
# inside model :
vt.f <- vt.forest("one", vt.o)
# use classification tree
vt.tr <- vt.tree("class", vt.f, threshold = c(0.01, 0.05))
# show subgroups
subgroups <- vt.subgroups(vt.tr)
# change options you'll be surprised !
subgroups <- vt.subgroups(vt.tr, verbose = TRUE, tables = TRUE)
