How is this with tidyverse 1.0? recode_nuts



  valid_different_codes <-  all_valid_nuts_codes %>%
      dplyr::filter_at( vars(tidyselect::all_of(geo_var)),                         ## should be changed with accross
                    dplyr::all_vars(. %in% different_codes)) %>%             ## and replacing . with rlang's  .data pronoun
    mutate ( years = as.numeric(gsub("code_", "" , .data$nuts )) )
