basic split - accessor functions

Code
  analysis(val_split)
Condition
  Error in `analysis()`:
  ! The initial validation split does not contain an analysis set.
  i You can access the training data with `training()`.

Code
  assessment(val_split)
Condition
  Error in `assessment()`:
  ! The initial validation split does not contain an assessment set.
  i You can access the testing data with `testing()`.

basic split stratified

Code
  initial_validation_split(dat, strata = does_not_exist)
Condition
  Error in `initial_validation_split()`:
  ! Can't select columns that don't exist.
  x Column `does_not_exist` doesn't exist.

Code
  initial_validation_split(dat, strata = c(x, f))
Condition
  Error in `initial_validation_split()`:
  ! Can't select columns that don't exist.
  x Column `x` doesn't exist.

Code
  initial_validation_split(dat, strata = rep(1:3, times = c(50, 25, 25)))
Condition
  Error in `initial_validation_split()`:
  ! Can't select columns past the end.
  i Location 3 doesn't exist.
  i There are only 2 columns.

grouped split - accessor functions

Code
  analysis(val_split)
Condition
  Error in `analysis()`:
  ! The initial validation split does not contain an analysis set.
  i You can access the training data with `training()`.

Code
  assessment(val_split)
Condition
  Error in `assessment()`:
  ! The initial validation split does not contain an assessment set.
  i You can access the testing data with `testing()`.

check_prop_3() works

Code
  check_prop_3(0.3)
Condition
  Error:
  ! `prop` needs to contain the proportions for training and validation.

Code
  check_prop_3("zero")
Condition
  Error:
  ! `prop` needs to be numeric.

Code
  check_prop_3(NULL)
Condition
  Error:
  ! `prop` needs to be numeric.

Code
  check_prop_3(NA)
Condition
  Error:
  ! `prop` needs to be numeric.

Code
  check_prop_3(0)
Condition
  Error:
  ! `prop` needs to contain the proportions for training and validation.

Code
  check_prop_3(c(0.3, NA))
Condition
  Error:
  ! `prop` cannot contain `NA`.

Code
  check_prop_3(c(0.3, NULL))
Condition
  Error:
  ! `prop` needs to contain the proportions for training and validation.

Code
  check_prop_3(c(0.3, 1))
Condition
  Error:
  ! Elements of `prop` need to be in (0, 1).

Code
  check_prop_3(c(0.3, 0.7))
Condition
  Error:
  ! The sum of the proportions in `prop` needs to be in (0, 1).
