Please have a look at these videos, courtesy of Akira Matsui, where you can see by yourself how to do most of the basic operations using GitHub Desktop and RStudio on a computer. They are helpful because they will save you precious time that trying to locate small things, such as where to click etc.
Note that the videos were created using older versions of GitHub Desktop and RStudio, which means that their respective interface will not be exactly the same as the one you see on your screen. This applies especially to GitHub Desktop which is now substantially different.

Be aware that your computer is different from my computer and from many others. So, please provide information about your working environment when you post a question.
R has a convenient function
sessionInfo() for this purpose. Here is the
information about my Mac. I ran the command
sessionInfo() at the R console
and copied and pasted the result. It takes less than 5 seconds so please do this
every time you ask a question.
