get_shap_values()
returns the matrix of SHAP values,
get_feature_values()
the data.frame
of feature values,
get_baseline()
the numeric baseline value, and
get_shap_interactions()
the SHAP interactions of the input.
For objects of class "mshapviz", these functions return lists of those elements.
S <- matrix(c(1, -1, -1, 1), ncol = 2, dimnames = list(NULL, c("x", "y")))
X <- data.frame(x = c("a", "b"), y = c(100, 10))
shp <- shapviz(S, X, baseline = 4)
get_shap_values(shp)
