Tutorial Videos

by Akira Matsui

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.

Good Practices

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.
