sappviz: Sector-Adjusted Points Plot for Feature Dominance
Visualizes feature influence by projecting data into 2D via PCA and adjusting points toward sector centers weighted by importances. Supports linear models and optionally tree-based models via SHAP values from the 'fastshap' package. For tree-based models, please install 'fastshap' manually from the CRAN archive: <https://cran.r-project.org/src/contrib/Archive/fastshap/>.
