The information here is obviously highly opinionated, and by no means gives the only correct way to do things. This is simply intended to be a quick primer for developers new to R, who have an interest in doing things well.
I originally created a similar version of this cheatsheet specifically for use in the UK Department for Education. This is a slightly more generalised version.
Feel free to adapt and use this cheatsheet for your own use, but please give credit! If you're using GitHub, the best way to do this is by creating a fork of this repo.
This cheatsheet is inspired by (and has now been added to) the cheatsheets created by Posit for other data science software.
