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
.
