bartMan is an R-package for investigating and visualising Bayesian Additive Regression Tree (BART) model fits. We construct conventional plots to analyze a model’s performance and stability as well as create new tree-based plots to analyze variable importance, interaction, and tree structure. We employ Value Suppressing Uncertainty Palettes (VSUP) to construct heatmaps that display variable importance and interactions jointly using color scale to represent posterior uncertainty. Our visualizations are designed to work with the most popular BART R packages available, namely BART, dbarts, and bartMachine. A practical example of the package in use can be found in our detailed vignette.


You can install the development version from GitHub with:
