To produce consistent conversion, some entries had to be removed from the conversion data frame. For example, the Correlates of War include 4 different codes to represent Western Germany. "countrycode" uses only one of them (CoW code 260 for all years). Similar choices were made in the cases of Korea, Yemen, Congo and Vietnam. Also, Namibia's iso2c code ("NA") can be understood as a missing observation (NA) by R.
Capitalized country names refer to the official short English names, as defined by the ISO organization. ISO does not publish official short English names for countries whose name is not capitalized in the the country.name vector. Continent and region information was taken from the UN website.
