Resurrecting the Tidynomicon

I didn’t know any R when I joined RStudio back in 2018, so my first project was to write a guide to the language for Python programmers. I set it aside when RStudio laid me off in 2021; a few bits are now out of date, but I have put it online anyway in the hope that it might be useful (and as a way to procrastinate when I should be revising my current project). As with all the technical writing on this site it is free to read and re-use under the CC-BY-NC license.
