v0.2.0 (CRAN)

App related changes

• Added vignette: Getting started with cheem.
• Added pkgdown site: https://nspyrison.github.io/cheem/.
• Added global model performance metrics to shiny app.
• In global_view(), added yhaty panel (residual plot/confusion matrix).
• In global_view(), added color options: log_maha.data and cor_attr.y.
• In cheem_radial_tour(), added regression case panel with additional fixed y of residual.
• In app radial tour inputs, added inclusion variable, subsetting variables used in radial tour.
• plotly::subplot() variants of global_view() & cheem_radial_tour().
• Added AmesHousing data, chocolates, and new toy simulated datasets (shiny app only).
• Reduced shiny app wording.

Internal & utilities

• Major rebase of cheem_ls().
• Added linear/logistic_tform() to suggest an alpha as a function of the number of observations.

Sourcing treeshap

• drat repository hosting treeshap did not work with debian and window rhub platforms;
• Minimally ported functions and cpp source files with @author & @source. Changed examples for consistency and smaller code base support.

v0.1.0 (GitHub only, commit 283da4)

Primary Preprocessing functions

• default_rf() create a randomForest::randomForest() with more conservative defaults.
• attr_df_treeshap() create treeshap::treeshap() local explanations of each observation.
• cheem_ls() create a cheem list of prepared tables for use in run_app().

Primary visual functions

• run_app() which is a shiny app consuming the following two:
• global_view() linked ‘plotly’ of approximations of data- and attribution-spaces with model information.
• cheem_radial_tour() create spinifex::ggtour of the specified radial tour. Consumed by animate_plotly, animate_gganimate, or filmstrip.
