Exercise

Replace safely() with possibly()

Once you have figured out how to solve an issue with safely(), (e.g., output an NA in place of an error), swap out safely() with possibly(). possibly() will run through your code and implement your desired changes without printing out the error messages.

You'll now map() over log() again, but you will use possibly() instead of safely() since you already know how to resolve your errors.
