assert_is_unsorted: Is the input unsorted?

Description

Checks to see if the input is unsorted (without the cost of sorting it).

Usage

assert_is_unsorted(
  x,
  na.rm = FALSE,
  strictly = FALSE,
  severity = getOption("assertive.severity", "stop")
)

is_unsorted(x, na.rm = FALSE, strictly = FALSE, .xname = get_name_in_parent(x))

Arguments

x

Input to check.

na.rm

If TRUE, remove NAs before checking.

strictly

If TRUE, equal values count as unsorted.

severity

How severe should the consequences of the assertion be? Either "stop", "warning", "message", or "none".

.xname

Not intended to be used directly.

Value

is_unsorted reimplements is.unsorted, providing more information on failure. assert_is_unsorted returns nothing but throws an error if is_unsorted returns FALSE.

is.unsorted.

Examples

Run this code
# NOT RUN {
assert_is_unsorted(c(1, 3, 2))
assert_is_unsorted(c(1, 1, 2), strictly = TRUE)
# These checks should fail.
assertive.base::dont_stop({
  assert_is_unsorted(c(1, 1, 2))
  assert_is_unsorted(c(2, 1, 0))
})
# }
