Adding a country column

The country codes in the ccode column are what's called Correlates of War codes. This isn't ideal for an analysis, since you'd like to work with recognizable country names.

You can use the countrycode package to translate. For example:

library(countrycode)

# Translate the country code 2
> countrycode(2, "cown", "country.name")
[1] "United States"

# Translate multiple country codes
> countrycode(c(2, 20, 40), "cown", "country.name")
[1] "United States" "Canada"        "Cuba"
