pipe arguments

Code
  rand_forest() %>% set_args()
Condition
  Error in `set_args()`:
  ! Please pass at least one named argument.

pipe engine

Code
  rand_forest() %>% set_mode()
Condition
  Error in `set_mode()`:
  ! Available modes for model type rand_forest are: "unknown", "classification", "regression", and "censored regression".

Code
  rand_forest() %>% set_mode(2)
Condition
  Error in `set_mode()`:
  ! 2 is not a known mode for model `rand_forest()`.

Code

can't set a mode that isn't allowed by the model spec

Code
  set_mode(linear_reg(), "classification")
Condition
  Error in `set_mode()`:
  ! "classification" is not a known mode for model `linear_reg()`.

unavailable modes for an engine and vice-versa

  i See `show_engines("linear_reg")`.

Code
  linear_reg() %>% set_engine()
Condition
  Error in `set_engine()`:
  ! Missing engine. Possible mode/engine combinations are: quantile regression {quantreg} and regression {lm, glm, glmnet, stan, spark, keras, brulee}.

Code

Condition
  Error in `set_engine()`:
  ! No known engines for `proportional_hazards()`.

set_* functions error when input isn't model_spec

Code
  set_mode(mtcars, "regression")
Condition
  Error in `set_mode()`:
  ! `set_mode()` expected a model specification to be supplied to the `object` argument, but received a(n) `data.frame` object.

Code
  set_args(mtcars, blah = "blah")
Condition
  Error in `set_args()`:
  ! `set_args()` expected a model specification to be supplied to the `object` argument, but received a(n) `data.frame` object.

Code
  bag_tree %>% set_mode("classification")
Condition
  Error in `set_mode()`:
  ! `set_mode()` expected a model specification to be supplied to the `object` argument, but received a(n) `function` object.
  i Did you mistakenly pass `model_function` rather than `model_function()`?

Code
  bag_tree %>% set_engine("rpart")
Condition
  Error in `set_engine()`:
  ! `set_engine()` expected a model specification to be supplied to the `object` argument, but received a(n) `function` object.
  i Did you mistakenly pass `model_function` rather than `model_function()`?

Code
  bag_tree %>% set_args(boop = "bop")
Condition
  Error in `set_args()`:
  ! `set_args()` expected a model specification to be supplied to the `object` argument, but received a(n) `function` object.
  i Did you mistakenly pass `model_function` rather than `model_function()`?

Code
  1L %>% set_args(mode = "classification")
Condition
  Error in `set_args()`:
  ! `set_args()` expected a model specification to be supplied to the `object` argument, but received a(n) `integer` object.

Code
  bag_tree %>% set_mode("classification")
Condition
  Error in `set_mode()`:
  ! `set_mode()` expected a model specification to be supplied to the `object` argument, but received a(n) `function` object.
