core function - correct input

Code
  range_check_func(as.character(x), -10, 110)
Condition
  Error in `range_check_func()`:
  ! `x` must be a numeric vector, not a character vector.

Code
  range_check_func(x, -10, 110, "a")
Condition
  Error in `range_check_func()`:
  ! `slack_prop` must be a numeric vector, not a string.

Code
  range_check_func(x, -10, 110, c(0.05, 0.08, 0.05))
Condition
  Error in `range_check_func()`:
  ! `slack_prop` should be of length 1 or 2, not 3.

core function - workings

Code
  range_check_func(x, 0, 100)
Condition
  Error in `range_check_func()`:
  i Smallest value of `x` is -10, crossing the lower bound -5.
  i Largest value of `x` is 110, crossing the upper bound 105.

Code
  range_check_func(x, 0, 110)
Condition
  Error in `range_check_func()`:
  i Smallest value of `x` is -10, crossing the lower bound -5.5.

Code
  range_check_func(x, -5, 100)
Condition
  Error in `range_check_func()`:
  i Largest value of `x` is 110, crossing the upper bound 105.25.

Code
  range_check_func(x, 0, 100, slack_prop = c(0.05, 0.1))
Condition
  Error in `range_check_func()`:
  i Smallest value of `x` is -10, crossing the lower bound -5.

Code
  range_check_func(x, 0, 100, slack_prop = c(0.1, 0.05))
Condition
  Error in `range_check_func()`:
  i Largest value of `x` is 110, crossing the upper bound 105.

Code
  range_check_func(x, 0, 100, warn = TRUE)
Condition
  Warning:
  i Smallest value of `x` is -10, crossing the lower bound -5.
  i Largest value of `x` is 110, crossing the upper bound 105.

in recipe

Code
  bake(rec2, test)
Condition
  Error in `range_check_func()`:
  i Smallest value of `x` is -10, crossing the lower bound -5.
  i Largest value of `x` is 110, crossing the upper bound 105.

Code
  bake(rec3, test)
Condition
  Warning:
  i Smallest value of `x` is -10, crossing the lower bound -5.
  i Largest value of `x` is 110, crossing the upper bound 105.
  Warning:
  i Smallest value of `y` is -10, crossing the lower bound -2.5.
  i Largest value of `y` is 60, crossing the upper bound 52.5.
Output
  # A tibble: 2 x 2
        x     y
    <dbl> <dbl>
  1   -10   -10
  2   110    60

Code
  bake(rec4, test)
Condition
  Error in `range_check_func()`:
  i Largest value of `y` is 60, crossing the upper bound 55.
