Dear all. Is it possible to convert.identify iso3 country names to the seven continent names?
# Asia, Africa, Antarctica, Australia, Europe, South America, and North America, I have tried the following: ### region <- merge(countryExData,df,by.x='ISO3V10',by.y='iso3') where df is the name of my dataset with iso3 the identification variable but there seems to be a a lot of missing values. Thank you!
