no assessment set

Code
  assessment(xx$splits[[1]])
Condition
  Error in `as.data.frame()`:
  ! There is no assessment data set for an `rsplit` object with class <perm_split>.

bad args

Code
  permutations(mtcars)
Condition
  Error in `permutations()`:
  ! You must specify at least one column to permute.

Code
  permutations(mtcars, foo)
Condition
  Error in `permutations()`:
  ! Can't select columns that don't exist.
  x Column `foo` doesn't exist.

Code
  permutations(mtcars, start_with("z"))
Condition
  Error in `permutations()`:
  i In argument: `start_with("z")`.
  Caused by error in `start_with()`:
  ! could not find function "start_with"

Code
  permutations(mtcars, everything())
Condition
  Error in `permutations()`:
  ! You have selected all columns to permute.
  i This effectively reorders the rows in the original data without changing the data structure.
  > Please select fewer columns to permute.
