Implemented in an easily installed package with a detailed vignette, treeheatr can be a useful teaching tool to enhance students' understanding of a simple decision tree model before diving into more complex tree-based machine learning methods. We have developed the treeheatr package to incorporate the functionality of ggparty but also utilize the leaf node space to display the data as a heatmap, a popular visualization that uncovers groups of samples and features in a dataset (Wilkinson and Friendly, 2009, Galili,T. The following lines of code compute and visualize the conditional decision tree along with the heatmap containing features that are important for constructing this model ( Fig. 1) : When the first argument x is a data.frame object representing the dataset instead of the decision tree, treeheatr automatically computes a conditional tree with default parameters for visualization.	./cache/cord-102588-vpu5w9wh.txt	./txt/cord-102588-vpu5w9wh.txt
