#' DEPRECATED FUNCTIONS FOR BACKWARD COMPATIBILITY
#' FUNCTIONS GIVE WARNING AND CALL APPROPRIATE regions FUNCTIONS

#' @title Add the statistical aggregation level to data frame
#' @description Eurostat regional statistics contain country, and various
#' regional level information.  In many cases, for example, when mapping,
#' it is useful to filter out national level data from NUTS2 level regional
#' data, for example.
#'
#' This function will be deprecated. Use the more comprehensive
#' `[regions::validate_nuts_regions()]` instead.
#'
#' @param dat A data frame or tibble returned by [get_eurostat()].
#' @param geo_labels A geographical label, defaults to `geo`.
#' @author Daniel Antal
#' @return a new numeric variable nuts_level with the numeric value of
#' NUTS level 0 (country), 1 (greater region),
#' 2 (region), 3 (small region).
