R Documentation

Check if an argument is TRUE

Description

Simply checks if an argument is TRUE.

Usage

checkTRUE(x, na.ok = FALSE)

check_true(x, na.ok = FALSE)

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

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

testTRUE(x, na.ok = FALSE)

test_true(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 assertTRUE./assert_true. return x invisibly, whereas checkTRUE./check_true. and testTRUE./test_true. return TRUE. If the check is not successful, assertTRUE./assert_true. throws an error message, testTRUE./test_true. returns FALSE, and checkTRUE./check_true. return a string with the error message. The function expect_true. always returns an expectation.
