Assert that the input vector has no missing values

This function asserts that the input vector has no missing values (NA) and aborts with an error message if it does.

Usage

assert_no_missing(x, msg = NULL, call = rlang::caller_env(), arg_name = NULL)

Arguments

x

A vector.

msg

A character string containing the error message to display if x has missing values.

call

Only relevant when pooling assertions into multi-assertion helper functions. See cli_abort for details.

arg_name

Advanced use only. Name of the argument passed (default: NULL, will automatically extract arg_name).

Value

invisible(TRUE) if x has no missing values (NA), otherwise aborts with the error message specified by msg

Examples

try({
assert_no_missing(c(1, 2, 3))  # Passes
assert_no_missing(c(1, NA, 2))  # Throws default error

assert_no_missing(c(1, 2, 3), msg = "Custom error message")  # Passes
assert_no_missing(c(1, NA, 2), msg = "Custom error message")  # Throws custom error
})
#> Error in eval(expr, envir) : 
#>   'c(1, NA, 2)' must have no missing values! Found 1
