23. Sort data by row
Summary

## Instruction

Sometimes, we want to order filtered data in a certain way. The arrange() function allows us to sort row data by the values in a given column. If we wanted to sort our data by population, we'd write:

arrange(countries, population)

## Exercise

Sort the rows in countries by area.

### Stuck? Here's a hint!

Type:

arrange(countries, area)
