PPtree node visualization

Description

Visualization tools to explore each node of PPtree

Usage

PPclassNodeViz(PPclassOBJ,node.id,Rule,legend,std,image,diff.prop)

Arguments

PPclassOBJ

PPregclass object

node.id

node ID

Rule

cutoff rule

legend

flag to represent legend in the plot. Default value is TRUE

std

flag to standardize data before drawing plot

image

flag to draw image plot of correlation matrix

diff.prop

percentage of number of variables with significant differences and shown in red in the bar chart style means
