Unnesting your data
As you've seen in the previous exercise, a nested data frame is simply a way to shape your data. Essentially taking the group_by() windows and packaging them in corresponding rows.
In the same way you can use the nest() function to break your data into nested chunks, you can use the unnest() function to expand the data frames that are nested in these chunks.
