Epidemiologist R Handbook
Coincidently, i found this interesting github repo the other day written in R that analyses the large drop in Covid cases in Mexico city after early treatment with Ivermectin:https://github.com/nasaul/paper_ivermectinaWhat really impressed me was how it stored the data in a google sheet, but the R-Studio program could still connect to google sheets trivially download the data (prompting the user to authenticate the app to google sheets). It was a nice experience.
