Exercise

Filtering summarized output

In the last exercise, you may have noticed that the country that voted least frequently, Zanzibar, had only 2 votes in the entire dataset. You certainly can't make any substantial conclusions based on that data!

Typically in a progressive analysis, when you find that a few of your observations have very little data while others have plenty, you set some threshold to filter them out.

Instructions

Use filter() to remove from the sorted data countries that have fewer than 100 votes.
