WebbThis package creates SHAP (SHapley Additive exPlanation) visualization plots for ‘XGBoost’ in R. It provides summary plot, dependence plot, interaction plot, and force plot and relies on the SHAP implementation provided by ‘XGBoost’ and ‘LightGBM’. Please refer to ‘slundberg/shap’ for the original implementation of SHAP in Python.
