0.2 Twitter credentials
The book uses Twitter data for a few exercises. I use the excellent rtweet package for accessing Twitter API. You will need an approved developer Twitter account and a functional Twitter app. Mike Kearly, the author of rtweet has a detailed post about how to set up an app and get the secret keys. you can follow it here: https://rtweet.info/articles/auth.html. However, the post is a bit old and the screenshots don’t look like the current Twitter menu. Although all his instructions are still valid, in this section I am showing you current screenshots.2
Step 1. Visit https://developer.twitter.com/ and request an account.
