Visualize subgroups

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

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)
