Version control has become essential for me keeping track of projects, as well as collaborating. It allows backup of scripts and easy collaboration on complex projects. RStudio works really well with Git, an open source open source distributed version control system, and GitHub, a web-based Git repository hosting service. I was always forget how to set up a repository, so here’s a reminder.

This example is done on RStudio Server, but the same procedure can be used for RStudio desktop. Git or similar needs to be installed first, which is straight forward to do.

Setup Git on RStudio and Associate with GitHub

In RStudio, Tools -> Version Control, select Git.

In RStudio, Tools -> Global Options, select Git//SVN tab. Ensure the path to the Git executable is correct. This is particularly important in Windows where it may not default correctly (e.g. C:/Program Files (x86)/Git/bin/git.exe).

2_rsaClose this window.

Click, View public key, and copy the displayed public key.

4_rsaIf you haven’t already, create a GitHub account. Open your account settings and click the SSH keys tab. Click Add SSH key. Paste in the public key you have copied from RStudio.

6_add_keyTell Git who you are. Remember Git is a piece of software running on your own computer. This is distinct to GitHub, which is the repository website. In RStudio, click Tools -> Shell … . Enter:

git config --global user.email "[email protected]"
git config --global user.name "ewenharrison"

Use your GitHub username.

Create New project AND git

In RStudio, click New project as normal. Click New Directory.

7_new_project

Name the project and check Create a git repository.

8_new_project_with_git

Now in RStudio, create a new script which you will add to your repository.

9_test_scriptAfter saving your new script (test.R), it should appear in the Git tab on the Environment / history panel.

11_initial_commitClick the file you wish to add, and the status should turn to a green ‘A’. Now click Commit and enter an identifying message in Commit message.

12_inital_commit2You have now committed the current version of this file to your repository on your computer/server. In the future you may wish to create branches to organise your work and help when collaborating.

Now you want to push the contents of this commit to GitHub, so it is also backed-up off site and available to collaborators. In GitHub, create a New repository, called here test.

5_create_git In RStudio, again click Tools -> Shell … . Enter:

git remote add origin https://github.com/ewenharrison/test.git
git config remote.origin.url [email protected]:ewenharrison/test.git
git pull -u origin master
git push -u origin master

13_push_pullYou have now pushed your commit to GitHub, and should be able to see your files in your GitHub account. The Pull Push buttons in RStudio will now also work. Remember, after each Commit, you have to Push to GitHub, this doesn’t happen automatically.

Clone an existing GitHub project to new RStudio project

In RStudio, click New project as normal. Click Version Control.

7_new_projectIn Clone Git Repository, enter the GitHub repository URL as per below. Change the project directory name if necessary.

14_new_version_controlIn RStudio, again click Tools -> Shell … . Enter:

git config remote.origin.url [email protected]:ewenharrison/test.git
