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.
