This R package provides a GUI for multinomial processing tree (MPT) models.

This package is currently broken/outdated and not recommended for practical use!

It is a plugin package for RKWard, a powerful GUI and IDE for R, and will only work in conjunction with RKWard. However, RKWard is free software, please check it out.


Installation via RKWard

After you installed RKWard, simply install this package like any other R package. The easiest way to get the most recent stable release is to use RKWard's package management:

After you installed the package, RKWard should immediately have additional menu entries -- there's usually no need to restart the application.

Installation via GitHub

To install it directly from GitHub, you can use install_github() from the devtools package:


You can safely ignore warnings about the (unavailable) package "rkward", it was installed together with RKWard.


See for documentation on writing plugins for RKWard. Contact [email protected] for help and requests.

This plugin is built using the rkwarddev package. This means that its development is mainly focussed on one script file, located at rk.MPT/inst/rkward/rkwarddev_MPT_plugin_script.R. This script is written in R code and generates all of the other plugin files when run. Therefore, in case you'd like to add to this plugin, please add to this script file.
