assert_all_are_nan

From assertive.numbers v0.0-2 by Richard Cotton

Is the input (not) NaN?

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

library(assertive.numbers)

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))
