# 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!
