printRandomForests {rattle}R Documentation

Print a representation of the Random Forest models to the console

Description

A randomForest model, by default, consists of 500 decision trees. This function walks through each tree and generates a set of rules which are printed to the console. This takes a considerable amount of time and is provided for users to access the actual model, but it is not yet used within the Rattle GUI. It may be used to display the output of the RF (but it takes longer to generate than the model itself!). Or it might only be used on export to PMML or SQL.

Usage

printRandomForests(model, models=NULL, include.class=NULL, format="")

Arguments

model

a randomForest model.

models

a list of integers limiting the models in MODEL that are displayed.

include.class

limit the output to the specific class.

format

possible values are "VB".
