Joining datasets with inner_join

In the first chapter, you created the votes_processed dataset, containing information about each country's votes. You'll now combine that with the new descriptions dataset, which includes topic information about each country, so that you can analyze votes within particular topics.

To do this, you'll make use of the inner_join() function from dplyr.
