I found recently, that in addition to a great list of cheatsheets designed by RStudio, one can also download a template for new cheatsheets from RStudio Cheat Sheets webpage.
With this template you can design your own cheatsheet, and submit it to the collection of Contributed Cheatsheets (Garrett Grolemund will help to improve the submission if needed).
Working on a new cheatsheet is pretty enjoying. You need to squeeze selected important stuff into a quite small surface like one or two pages.
Lots of fun.
I did it for eurostat and survminer packages (cheatsheets below).
And would love to see one for caret.
