[R-sig-Geo] ISO3 to 7 continents names

For matching up country names, it's hard to beat the package "countrycode".  It allows conversion across many different country codes and country names, and it also has continents.

Hard to help you here without seeing at least some of your data, or at least the rows that didn't match. Maybe you've got invalid codes in your data? How can we tell?

Also, you should say where countryExData comes from, I had to guess it was from the rworldmap package. That data frame doesn't have the "continent" in it, so what use is it to you?
