is_logical: Is the input logical?

In assertive.types: Assertions to Check Types of Variables

Description

Checks to see if the input is logical.

Usage

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

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

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

is_logical(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_logical wraps is.logical, providing more information on failure. is_a_bool returns TRUE if the input is logical and scalar. The assert_* functions return nothing but throw an error if the corresponding is_* function returns FALSE.
