Plotting just the UK over time

Now that you have the percentage of time that each country voted "yes" within each year, you can plot the trend for a particular country. In this case, you'll look at the trend for just the United Kingdom.

This will involve using filter() on your data before giving it to ggplot2.

  summarize(total = n(),
            percent_yes = mean(vote == 1))

# Print by_year_country


# Create a filtered version: UK_by_year


# Line plot of percent_yes over time for UK only
