In SHAPforxgboost: SHAP Plots for 'XGBoost'

Make the SHAP force plot

Description

The force/stack plot, optional to zoom in at certain x-axis location or zoom in a specific cluster of observations.

Usage

shap.plot.force_plot(
  shapobs,
  id = "sorted_id",
  zoom_in_location = NULL,
  y_parent_limit = NULL,
  y_zoomin_limit = NULL,
  zoom_in = TRUE,
  zoom_in_group = NULL
)

Arguments

shapobs	The dataset obtained by shap.prep.stack.data.
id	the id variable.
zoom_in_location	where to zoom in, default at place of 60 percent of the data.
y_parent_limit	set y-axis limits.
y_zoomin_limit	c(a,b) to limit the y-axis in zoom-in.
zoom_in	default to TRUE, zoom in by ggforce::facet_zoom.
zoom_in_group	optional to zoom in certain cluster.

Examples

# **SHAP force plot**
plot_data <- shap.prep.stack.data(shap_contrib = shap_values_iris,
                                  n_groups = 4)
shap.plot.force_plot(plot_data)
shap.plot.force_plot(plot_data,  zoom_in_group = 2)

# plot all the clusters:
shap.plot.force_plot_bygroup(plot_data)
