Arguments

cheem_ls	The return of a cheem_ls() call.
rownumbers	A vector of the numeric index of rownumbers to keep. To use a logical index, pass it to which(), eg. idx <- which(mtcars$mpg > 30).

## Classification setup
X    <- spinifex::penguins_na.rm[, 1:4]
Y    <- spinifex::penguins_na.rm$species
clas <- spinifex::penguins_na.rm$species

## Cheem
peng_chm <- cheem_ls(X, Y, penguin_xgb_shap, penguin_xgb_pred, clas,
                     label = "Penguins, xgb, shapviz")
lapply(peng_chm, NROW)

## subset a cheem list
num_idx <- which(spinifex::penguins_na.rm$flipper_length_mm > 185)
peng_chm_sub <- subset_cheem(peng_chm, num_idx)
lapply(peng_chm_sub, NROW)
## Notice that $global_view_df and $decode_df have fewer rows.
