In tidymodels/themis: Extra Recipes Steps for Dealing with Unbalanced Data

bad data

Code
  rec %>% step_nearmiss(x) %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  ! `x` should be a factor variable.

Code
  rec %>% step_nearmiss(class, id) %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  ! The selector should select at most a single variable.

errors if character are present

Code
  recipe(~., data = df_char) %>% step_nearmiss(x) %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  x All columns selected for the step should be double or integer.
  * 1 factor variable found: `y`

NA in response

Code
  recipe(Job ~ Age, data = credit_data) %>% step_nearmiss(Job) %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  ! Cannot have any missing values. NAs found in Job.

bad args

Code
  recipe(~., data = mtcars) %>% step_nearmiss(over_ratio = "yes") %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  ! The following argument was specified but do not exist: `over_ratio`.

Code
  recipe(~., data = mtcars) %>% step_nearmiss(neighbors = TRUE) %>% prep()
Condition
  Error in `step_nearmiss()`:
  Caused by error in `prep()`:
  ! `neighbors` must be a whole number, not `TRUE`.

Code
  recipe(~., data = mtcars) %>% step_nearmiss(seed = TRUE)
Condition
  Error in `step_nearmiss()`:
  ! `seed` must be a whole number, not `TRUE`.

bake method errors when needed non-standard role columns are missing

Code
  bake(trained, new_data = circle_example[, -3])
Condition
  Error in `step_nearmiss()`:
  ! The following required column is missing from `new_data`: class.
