Selecting a county from each region

Previously, you used the walk column, which offers a percentage of people in each county that walk to work, to add a new column and count to find the total number of people who walk to work in each county.

Now, you're interested in finding the county within each region with the highest percentage of citizens who walk to work. 

counties_selected <- counties %>%
  select(region, state, county, metro, population, walk)
