Exercise

Unnesting a data frame

You now have a tidied version of each model stored in the tidied column. You want to combine all of those into a large data frame, similar to how you combined the US and UK tidied models earlier. Recall that the unnest() function from tidyr achieves this.

Instructions

Add an unnest() step to unnest the tidied models stored in the tidied column. Save the result as country_coefficients.
Print the resulting country_coefficients object to the console.
