Examples

if (FALSE) {

# build a regression model stack
st <-
  stacks() |>
  add_candidates(reg_res_lr) |>
  add_candidates(reg_res_sp) |>
  blend_predictions() |>
  fit_members()

# remove any of the "butcherable"
# elements individually
axe_call(st)
axe_ctrl(st)
axe_data(st)
axe_fitted(st)
axe_env(st)

# or do it all at once!
butchered_st <- butcher(st, verbose = TRUE)
