Where do we recommend that folks move from typing in the console to writing the exercises in a script? It seems like the beginning of the Data Cleaning and Transformation Lesson would be a good place to do this. Perhaps we could also mention some best practices about creating R scripts (adding names and dates) and when you would type something in the console versus save in a script. We might also want to refresh their memory on how to run code chunks (covered in the very first episode).
