In treeClust: Cluster Distances Through Trees

Description

This function builds one tree, as part of a treeClust analysis. It will not normally be called by users.

Usage

treeClust.rpart(i, dfx, d.num, control, rcontrol)

Arguments

i	Index of column number (in dfx) of response variable.
dfx	Data set used to build tree
d.num	Distance number, 1-4, describing measurement for clustering.
control	List of controls for treeClust, often output of treeClust.control().
rcontrol	List of controls for rpart, often output of rpart.control().

Details

It is useful to encapsulate some of the tree-building code so that it can be used either in a loop or in parallel.

Value

List containing some of these elements (below). Size and DevRatio are always present.

DevRat	Deviance ratio (decrease in dev. / original dev.) for this tree; always present
Size	Size of pruned tree. If no tree is grown, Size is 1.
