countrycode standardizes country names, converts them into ~40
different coding schemes, and assigns region descriptors. Scroll down

If you use countrycode in your research, we would be very grateful if
you could cite our paper:
Arel-Bundock, Vincent, Nils Enevoldsen, and CJ Yetman, (2018). countrycode: An R package to convert country names and country codes. Journal of Open Source Software, 3(28), 848, https://doi.org/10.21105/joss.00848
Different data sources use different coding schemes to represent countries (e.g. CoW or ISO). This poses two main problems: (1) some of these coding schemes are less than intuitive, and (2) merging these data requires converting from one coding scheme to another, or from long country names to a coding scheme.
The countrycode function can convert to and from 40+ different country
coding schemes, and to 600+ variants of country names in different
languages and formats. It uses regular expressions to convert long
country names (e.g. Sri Lanka) into any of those coding schemes or
country names. It can create new variables with various regional
groupings.
From the R console, type:
install.packages("countrycode")To install the latest development version, you can use the remotes
package:
library(remotes)
