In assertions: Simple Assertions for Beautiful and Customisable Error Messages

Assert that the input vector has no missing values

Description

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
})
