Examples

library(cheem)

## Attribution basis of the primary instance
sug_basis(ames_rf_shap, rownum = 1)


## This can be used to find a basis to start the radial tour.
# ?radial_cheem_tour

## Regression setup:
dat  <- amesHousing2018_NorthAmes
X    <- dat[, 1:9]
Y    <- dat$SalePrice
clas <- dat$SubclassMS

## radial_cheem_tour()
ames_rf_chm <- cheem_ls(X, Y, ames_rf_shap, ames_rf_pred, clas,
                        label = "North Ames, RF, SHAP")
bas <- sug_basis(ames_rf_shap, 1)
mv  <- sug_manip_var(ames_rf_shap, 1, 2)
ggt <- radial_cheem_tour(ames_rf_chm, basis = bas, manip_var = mv)
