In workflows: Modeling Workflows

workflow must be the first argument when adding actions

Code
  add_formula(1, mpg ~ cyl)
Condition
  Error in `add_formula()`:
  ! `x` must be a workflow, not a <numeric>.

Code
  add_recipe(1, rec)
Condition
  Error in `add_recipe()`:
  ! `x` must be a workflow, not a <numeric>.

Code
  add_model(1, mod)
Condition
  Error in `add_model()`:
  ! `x` must be a workflow, not a <numeric>.

confirms compatibility of model and tailor

Code
  workflow(preprocessor = mpg ~ cyl, spec = parsnip::linear_reg(), postprocessor = tailor)
Condition
  Error in `workflow()`:
  ! The model mode "regression" and the tailor type "binary" are incompatible.

model spec is validated

Code
  workflow(spec = 1)
Condition
  Error in `add_model()`:
  ! `spec` must be a <model_spec>.

preprocessor is validated

Code
  workflow(preprocessor = 1)
Condition
  Error in `workflow()`:
  ! `preprocessor` must be a formula, recipe, or a set of workflow variables.

postprocessor is validated

Code
  workflow(postprocessor = 1)
Condition
  Error in `workflow()`:
  ! `postprocessor` must be a <tailor>.

constructor validates input

Code
  new_workflow(pre = 1)
Condition
  Error in `new_workflow()`:
  ! `pre` must be a `stage`.

Code
  new_workflow(fit = 1)
Condition
  Error in `new_workflow()`:
  ! `fit` must be a `stage`.

Code
  new_workflow(post = 1)
Condition
  Error in `new_workflow()`:
  ! `post` must be a `stage`.

Code
  new_workflow(trained = 1)
Condition
  Error in `new_workflow()`:
  ! `trained` must be a single logical value.

input must be a workflow

`x` must be a workflow, not a <numeric>.
