R Documentation

Check if an argument is FALSE

Description

Simply checks if an argument is FALSE.

Usage

checkFALSE(x, na.ok = FALSE)

check_false(x, na.ok = FALSE)

assertFALSE(x, na.ok = FALSE, .var.name = vname(x), add = NULL)

assert_false(x, na.ok = FALSE, .var.name = vname(x), add = NULL)

testFALSE(x, na.ok = FALSE)

test_false(x, na.ok = FALSE)

Arguments

`x`	[any] Object to check.
`na.ok`	[`logical(1)`] Are missing values allowed? Default is `FALSE`.
`.var.name`	[`character(1)`] Name of the checked object to print in assertions. Defaults to the heuristic implemented in `vname`.
`add`	[`AssertCollection`] Collection to store assertion messages. See `AssertCollection`.

Value

Depending on the function prefix: If the check is successful, the functions assertFALSE./assert_false. return x invisibly, whereas checkFALSE./check_false. and testFALSE./test_false. return TRUE. If the check is not successful, assertFALSE./assert_false. throws an error message, testFALSE./test_false. returns FALSE, and checkFALSE./check_false. return a string with the error message. The function expect_false. always returns an expectation.
