Exercise

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.

Instructions

  • Load the dplyr package.
  • Print the votes_processed dataset.
  • Print the new descriptions dataset.
  • Join the two datasets using dplyr's inner_join(), using the rcid and session columns to match them. Save as votes_joined.
