The rainfall package lets you download data on monthly average rainfall levels on a country level. The data comes from the Climate Research Unit at the University of East Anglia.

The package is available on GitHub where you also find more information on installation & usage.


The package recodepolity implements the corrections to the Polity IV dataset proposed by Vreeland (2008) and Plümper and Neumayer (2010).
