In orbital: Predict with 'tidymodels' Workflows in Databases

orbital errors on non-trained workflow

Code
  orbital(wf_spec)
Condition
  Error in `orbital()`:
  ! `x` must be a fully trained <workflow>.

orbital errors untrained recipe

Code
  orbital(rec_spec)
Condition
  Error in `orbital()`:
  ! recipe must be fully trained.

orbital errors on non-trained parsnip

Code
  orbital(lm_spec)
Condition
  Error in `orbital()`:
  ! `x` must be fitted model.

orbital errors nicely on post-processing

Code
  orbital(wf_fit)
Condition
  Error in `orbital()`:
  ! post-processing is not yet supported in orbital.

orbital errors on wrong input

Code
  orbital(lm(mpg ~ ., data = mtcars))
Condition
  Error in `orbital()`:
  ! Is not implemented for a <lm> object.

orbital printing works

Code
  orbital(wf_fit)
