I was happy to make a contribution of a new cheatsheet in support of RStudio.
The cheatsheet covers the use of Git and GitHub in RStudio.
Many high quality cheatsheets on R topics have been generously contributed by R users and are available here.
Some cheatsheets are also available in the RStudio IDE under Help > Cheatsheets
You may visit the Cheatsheet GitHub Repository by following this link.
