assert_all_are_finite: Are the inputs (in)finite?

Description

Checks to see if the inputs are (in)finite.

Usage

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


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


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


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


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


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


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


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


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


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


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


is_positive_infinity(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_finite wraps is.finite, showing the names of the inputs in the answer. is_infinite works likewise for is.infinite. The assert_* functions return nothing but throw an error if the corresponding is_* function returns FALSE.
