#' @title Checks if values are outside of an interval (open on the

#' @description This function checks if the values in the `x`

#'   `NA` values are treated as "not in the interval".
#' @param x A vector of values. (Lists will be coerced to a numeric vector.)
#' @param lo Left end of the interval.

#' @return A boolean vector of the same length as `x`.
