cheem v0.4.0

  • Repaired packagedown site!
  • Fixed news on packagedown site.
  • Shiny app has go buttons rather than waiting after every input change.
  • Shiny app text, plot dimensions, and text cleaned up.
  • Classification tour now uses a horizontal layout.
  • Cleaned up the text on the facet panels for global_tour() and radial_cheem_tour().
  • Removed support for the basis_type argument. support for alternative bases types is really an extension of the analysis.
  • Recreate the saved classification model, they fit too well to work as illustrations.
  • Set seed more consistently. All model and attribution shifted a bit, but will be more replicable going forward.
  • Minor documentation and code clean up and clarifications.

cheem v0.3.0 – Generalized for any attribution

CRAN release: 2023-05-08

  • Rebase all functions from expecting a unified treeshap::shap() to generalized data frame or matrix format for arbitrary attribution spaces.
  • Rework vignette and examples to reflect this change.
  • Added precomputed predictions and attributions for the Ames, Chocolates, and Penguins datasets. This allows users to run attribution-agnostic functions without dependencies.
  • Add subset_cheem(), a convenience function for subsetting cheem lists after construction.
  • Removed plotly subplot variations of visuals: global_view_subplots(), radial_cheem_tour_subplots(). These were development variations never used in the shiny app.
  • Minor function renames for parsimony and consistency.

cheem v0.2.0 (CRAN releases here on out)

CRAN release: 2022-03-14

  • 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.
  • as of v0.3.0, cheem was generalized to all local variable attributions, so this is not a concern.

cheem 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.
