Package options for glex plots

The color choices used across all glex visualization functions can be adjusted globally via options():

Details

glex.palette

(NULL) Diverging palette used to color continuous interaction effects in plot_twoway_effects() and plot_threeway_effects(). The default NULL uses a blue/red gradient built from glex.colors_sign, matching the look of the Python shap and shapiq packages. Set to the name of a diverging scico palette (e.g. "vik", "roma") to use that instead.

glex.palette_discrete

("Dark2") Discrete palette used to color categorical predictors in interaction plots. Accepts a vector of colors (used via ggplot2::scale_color_manual()), the string "okabe-ito" (the colorblind-safe Okabe-Ito palette via grDevices::palette.colors()), the name of a scico palette, or the name of an RColorBrewer palette.

glex.colors_sign

(c("#008BFB", "#FF0051")) Two colors for negative and positive contributions in glex_explain(), also used as the endpoints of the default continuous gradient. The defaults follow the blue/red convention familiar from the Python shap and shapiq packages.

glex.color_line

("#194155") Color for main effect lines and columns drawn by autoplot() and plot_pdp().

Examples

# Use a scico palette for continuous effects instead of the default gradient
options(glex.palette = "roma")

# Restore the default shap-style gradient
options(glex.palette = NULL)

# Categorical predictors: Okabe-Ito, a scico/brewer palette, or custom colors
options(glex.palette_discrete = "okabe-ito")
options(glex.palette_discrete = "batlow")
options(glex.palette_discrete = c("#E69F00", "#56B4E9", "#009E73"))
