This data.frame corresponds to version 2.0.0 of the "Admin 0 - Countries" map from naturalearthdata.com The data.frame was modified by removing columns with non-ASCII characters. Also, I added a column called "region" which is the the all lowercase version of the column "sovereignt".
Note that due to the resolution of the map (1:110m, or 1 cm=1,100 km), small countries are not represented on this map. See ?country.names for a list of all countries represented on the map.
