partykit: A Toolkit for Recursive Partytioning

An add-on package to the R system for statistical computing distributed under the GPL-2 | GPL-3 License at the Comprehensive R Archive Network

Description

A toolkit with infrastructure for representing, summarizing, and visualizing tree-structured regression and classification models. This unified infrastructure can be used for reading/coercing tree models from different sources (rpart, RWeka, PMML) yielding objects that share functionality for print/plot/predict methods. Furthermore, new and improved reimplementations of conditional inference trees (ctree) and model-based recursive partitioning (mob) from the party package are provided based on the new infrastructure.
