R/validate_nuts_countries.R
validate_nuts_countries.RdThis function is mainly a wrapper around the well-known countrycode function, with three exception that are particular to the European Union statistical nomenclature.
validate_nuts_countries(dat, geo_var = "geo")A data frame with a 2-character geo variable to be validated
Defaults to "geo". The variable that contains the
2 character geo codes to be validated.
The original data frame extended with the column 'typology'.
This column states 'country' for valid country typology coding, or
appropriate label for invalid ISO-3166-alpha-2 and ISO-3166-alpha-3 codes.
All ISO-3166-1 country codes are validated, and also the three exceptions.
Treated valid, because NUTS uses EL instead of GR for Greece since 2010.
Treated valid, because NUTS uses UK instead of GB for the United Kingdom.
XK is used for Kosovo, because Eurostat uses this code, too.
Other validate functions:
validate_nuts_regions()
{
my_dat <- data.frame (
geo = c("AL", "GR", "XK", "EL", "UK", "GB", "NLD", "ZZ" ),
values = runif(8)
)
## NLD is an ISO 3-character code and is not validated.
