validate_nuts_countries: Validate Conformity with NUTS Country Codes
In regions: Processing Regional Statistics

Description Usage Arguments Value See Also Examples

This function is mainly a wrapper around the well-known countrycode function, with three exception that are particular to the European Union statistical nomenclature.

EL: Treated valid, because NUTS uses EL instead of GR for Greece since 2010.
UK: Treated valid, because NUTS uses UK instead of GB for the United Kingdom.
XK: XK is used for Kosovo, because Eurostat uses this code, too.

All ISO-3166-1 country codes are validated, and also the three exceptions.

1	validate_nuts_countries(dat, geo_var = "geo")

`dat`	A data frame with a 2-character geo variable to be validated
`geo_var`	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.

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.
 validate_nuts_countries(my_dat)
