Check if an argument is TRUE
Simply checks if an argument is TRUE.
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)
x |
[any] |
na.ok |
[ |
.var.name |
[ |
add |

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. returns a string with the error message.
The function expect_true. always returns an
expectation.
testTRUE(TRUE) testTRUE(FALSE)
