purrr and scatterplots

Since ggplot() does not accept lists as an input, it can be paired up with purrr to go from a list to a dataframe to a ggplot() graph in just a few lines of code.

You will continue to work with the gh_users data for this exercise. You will use a map_*() function to pull out a few of the named elements and transform them into the correct datatype. Then create a scatterplot that compares the user's number of followers to the user's number of public repositories.

  • map() over gh_users, use the map_*() function that creates a dataframe, with four columns, named "login", "name", "followers" and "public_repos".
  • Pipe that dataframe into a scatterplot, where the x axis is followers and y is public_repos.
