assert_all_are_nan {assertive.numbers}R Documentation

Is the input (not) NaN?

Description

Checks to see if the input is a number that is(n't) NaN.

Usage

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

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

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

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

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

is_not_nan(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_nan wraps is.nan, coercing the input to numeric if necessary. is_not_nan works similarly, but returns the negation. The assert_* functions return nothing but throw an error if the corresponding is_* function returns FALSE.

Examples

x <- c(0, NaN, NA)
is_nan(x)
is_not_nan(x)
assert_all_are_not_nan(1:10)
assert_any_are_not_nan(x)
assertive.base::dont_stop(assert_all_are_not_nan(x))
