assert_is_if_condition(x, severity = getOption("assertive.severity", "stop"))

is_if_condition(x, .xname = get_name_in_parent(x))

Arguments

x

Input to check.

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_if_condition returns TRUE if the input is scalar TRUE or FALSE.

Note

if will try to do the right thing if you pass it a number or a string, but this function assumes you want to do the right thing and pass either TRUE or FALSE, maybe with some attributes.
