SORTEE Peer code review

Hi, I thought I'd start to look at the code before the code review. Some quick comments below:

• The code runs and does what I expected it to do!
• The .Rmd for 01 seems to be missing
• It might be good to consider adding some folder structure to "clean up" the repo a bit - you could put all the rmd files in one folder called "scripts" to help users navigate to them for example
• It might be worth considering using renv to make sure that the libraries needed are loaded and are the correct version to rerun the analysis in 2 or 5 years time. It will also help the user to ensure they all have the right packages installed before they try and run the code
