Is the vector monotonically increasing or decreasing?
Checks to see if the input is monotonically increasing or decreasing.
assert_is_monotonic_increasing(x, strictly = FALSE,
severity = getOption("assertive.severity", "stop"))
assert_is_monotonic_decreasing(x, strictly = FALSE,
severity = getOption("assertive.severity", "stop"))
is_monotonic_increasing(x, strictly = FALSE, .xname = get_name_in_parent(x))
is_monotonic_decreasing(x, strictly = FALSE, .xname = get_name_in_parent(x))x |
Input to check. |
strictly |
Logical. If |
severity |
How severe should the consequences of the assertion be?
Either |
