Friendly Reminders

– single pipeline: no “breaks” in your code. Start with your data and use pipes until the finished product

– saving a variable: using the assignment arrow <- to save output as a variable

– eval: false is a code chunk argument to have the code not run when you render your doc. Often used when we put incomplete or fill in blank code for you to edit. Make sure to remove this when you have finalized the code. This error can be caught if you look at your rendered doc!

Data Format (Wide vs Long)

– Wide data contains values that do not repeat in the first column

– Long data contains values that do repeat in the first column
