tree.segme {denpro}R Documentation

Returns the segmentation of the nodes of a visualization tree

Description

Returns the segmentation of the nodes of a visualization tree. When the visualization tree is a tail tree, finds a grouping for the observations. The grouping may be used to enhance scatter plots, graphical matrices, and parallel coordinate plots.

Usage

tree.segme(tt, paletti = NULL, pcf = NULL)

Arguments

tt visualization tree; for example a tail tree
paletti a sequence of numbers or colors (group labels)
pcf internal; piecewise constant function

Value

Vector of length n, where n is the number of nodes in the visualization tree. The elements of the vector give the segmentation labels.
