Set iso3 for Kosovo to XKX

[jrspringman]

Is it possible to get the iso3 for Kosovo set to XKX? Not all countries recognize Kosovo's independence, but many datasets treat it as an independent country.

The string Kosovo returns the following warning and yields NA values. Warning messages: 1: Problem while computing iso3 = countrycode::countrycode(country, "country.name", "iso3c"). ℹ Some values were not matched unambiguously: Kosovo

The built-in code sets follow precisely the standards as defined by each code sets' primary maintainer. So for instance, the International Organization for Standardization does not include Kosovo/XKX in its ISO 3166-1 alpha-3 standard, therefore {countrycode} will not include that in its iso3c origin/destination code set.

You can easily add custom codes for specific countries like this...

library(countrycode)
country_names <- c('Greece', 'United Kingdom', 'Kosovo', 'France')
countrycode(country_names, 
            origin = 'country.name', 
            destination = 'iso3c', 
            custom_match = c(`Kosovo` = 'XKX'))
#> [1] "GRC" "GBR" "XKX" "FRA"
