Questions about gh_repos

You're going to use gh_repos again, a list where each element is information about a GitHub repository. Here you will use map() and map_dbl() to answer the question:

  • Which repository is the largest?'

GitHub repository size is measured in megabytes. This information could be useful to document if you are working with a list based dataset that changes over time, and need to be able to pull out information, like the largest repository, in the most recent dataset.
