checkmate (version 1.9.3)

checkFALSE: 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. returns a string with the error message. The function expect_false. always returns an expectation.

Examples

# NOT RUN {
testFALSE(FALSE)
testFALSE(TRUE)
# }
