assertive (version 0.1-7)

assert_all_are_nan: 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)

  assert_any_are_nan(x)

  assert_all_are_not_nan(x)

  assert_any_are_not_nan(x)

  is_nan(x)

  is_not_nan(x)

Arguments

x

Input to check.

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

assert_all_are_not_nan(1:10)
assert_any_are_not_nan(c(NaN, 1))
