check_new_data works

Code
  bake(log_obj, examples[, 2:4, drop = FALSE])
Condition
  Error in `step_log()`:
  ! The following required column is missing from `new_data`: V1.

Code
  bake(log_obj, examples[, 3:4, drop = FALSE])
Condition
  Error in `step_log()`:
  ! The following required columns are missing from `new_data`: V1 and V2.

Code
  bake(log_obj, examples[, 4, drop = FALSE])
Condition
  Error in `step_log()`:
  ! The following required columns are missing from `new_data`: V1, V2, and V3.

conditionMessage method for recipes errors works

Code
  conditionMessage(attr(res, "condition"))
Output
  [1] "Error in `step_dummy()`:\nCaused by error in `prep()`:\nx All columns selected for the step should be factor or ordered.\n* 11 double variables found: `mpg`, `cyl`, `disp`, `hp`, ..."

validate_training_data errors are thrown

Code
  recipe(~., data = mtcars) %>% prep(fresh = TRUE)
Condition
  Error in `prep()`:
  ! A training set must be supplied to the `training` argument when `fresh = TRUE`.

Code
  recipe(~., data = mtcars) %>% prep(mtcars[, 1:2], fresh = TRUE)
Condition
  Error in `prep()`:
  ! Not all variables in the recipe are present in the supplied training set: `disp`, `hp`, `drat`, `wt`, `qsec`, `vs`, `am`, `gear`, and `carb`.

Code
  recipe(~., data = mtcars) %>% step_center(disp) %>% prep(retain = FALSE) %>%
    prep(mtcars, fresh = FALSE)
Condition
  Error in `prep()`:
  ! To prep new steps after prepping the original recipe, `retain = TRUE` must be set each time that the recipe is trained.

Code
  tmp <- recipe(~., data = mtcars) %>% step_center(disp) %>% prep() %>% prep(
    mtcars)
Condition
  Warning in `prep()`:
  ! The previous data will be used by `prep()`.
  i The data passed using `training` will be ignored.

spline error messages

Code
  recipes:::spline_msg("Error in if (df < 0) { : missing blah blah\n")
Condition
  Error in `recipes:::spline_msg()`:
  ! Error in if (df < 0) { : missing blah blah

Code
  recipes:::spline_msg("craaazzyy {{}}{}{}")
Condition
  Error in `recipes:::spline_msg()`:
  ! craaazzyy {{}}{}{}

names0() error on non-positive number

Code
  names0(0)
Condition
  Error:
  ! `num` must be a whole number larger than or equal to 1, not the number 0.

ellipse_check() errors on empty selection

Code

Condition
  Error in `ellipse_check()`:
  ! Please supply at least one variable specification.
  i See ?selections (`?recipes::selections()`) for more information.

Code
  uses_dim_red(x)
Condition
  Error in `uses_dim_red()`:
  ! Recipes version >= 0.1.17 represents the estimates using a different format. Please recreate this recipe or use version 0.1.16 or less. See issue #823 (<https://github.com/tidymodels/recipes/issues/823>).
