Exercise

Summarizing the full dataset

In this analysis, you're going to focus on "% of votes that are yes" as a metric for the "agreeableness" of countries.

You'll start by finding this summary for the entire dataset: the fraction of all votes in their history that were "yes". Note that within your call to summarize(), you can use n() to find the total number of votes and mean(vote == 1) to find the fraction of "yes" votes.
