Support for regions, subnational entities, and other non-countries.
The codelist already includes many regional groupings (e.g., UN and World Bank regions, various continent designations, etc.)
Since the number of potential groupings is infinite, and since there is no standardization, we cannot support all possible region designations.
The best approach is to use the custom_dict argument.
If you would like to submit a CSV file with different groupings, please open a new issue and we can discuss if it makes sense to distribute it in the countrycode package.
Many-to-One mapping
Some countries have multiple codes. For example, in cowc, Germany could be 255 or 260, depending on the time period we are looking at. Currently, countrycode works with a strict one-to-one mapping of codes to countries. Therefore, countrycode() can only recognize one of the codes -- typically the latest one.
The recommended approach is to use the countrycode_panel and to "left-merge" your country-year data directly there.
The countrycode maintainers are interested in implementing a more robust infrastructure for many-to-one mapping. If you have ideas for implementation and/or energy to submit code, please contribute to this thread: https://github.com/vincentarelbundock/countrycode/issues/186
