Summary

Instruction

Great! But what if we want our data in reverse order? Then we use desc() inside the arrange() function. If we wanted to see a list of European countries with the least-populated ones first, we'd write:

countries %>%
  filter(continent == "Europe") %>%
  arrange(desc(population))

Exercise

Select countries from Africa, and sort the results in descending order by area.

Stuck? Here's a hint!

Type:

countries %>%
  filter(continent == "Africa") %>%
  arrange(desc(area))
