GitHub is an online code repository that is maintained by Microsoft. It is an excellent, free-to-use repository that allows you to save, update, and share scripts and output. It is useful for many things, including:
- Version control, keep track of old versions of your scripts and track how you have updated them.
- Code repository, a useful system for storing and disseminating code. It is an effective way to distribute programs or allow people to check your work.
- Collaborative coding, upload your work on a collaboratively-coded script or download your colleagues’ recent work. Helps prevent a situation in which a team is working on different versions of a script
I’m sure that there are other great uses. If you want to share ideas with your colleagues, you can add them below in the comments section.
This tutorial is adapted from a tutorial from the University of Chicago. Readers should visit that site for a more detailed walk-through.
Start a Git Repository
On GitHub.com, create a “New Repository” (look for a green button). Click the green button to start an archive

Create a new repository. Make the repository public, and initialize it WITH a README file.

Create a Project Connected to the Repository
Click File > New Project > Version Control > Git


You will then be asked for this information. In the bottom field, name the folder that will contain your new project folder. In the middle field, give your project a name. The top field requires the URL for this project’s associated Git.

You can get the address for your Github repostory by visitng the repository, clicking the green button, and getting the HTTPS clone address. Add that address to the top line.

Complete the information to create the R Project file.

You have now created a project. It will remember the state of your RStudio session when you exit, and will bring it up again when you open the project again in the Project menu:

Push Your Scripts or Script Changes to GitHub
Select the file you wish to upload, and click “commit”


Fill out the popup window. Write a comment and click “Commit”. Then “Push”

Et voila!, your script is posted to GitHub!
