• If you have trouble accessing the file via the URL, you can just download the data file from Github directly, making sure to load the file into R using the hashed out code in Lines6-7.

Then to run, copy the full code (below), OR download the source file from github ,
OR, the easiest way, run this quick code directly:

Full script here.
