Downloading course materials using Git with RStudio

You can use Git within RStudio to download the course materials. If you haven't cloned the repository before, follow these instructions:

1. Click on the green "Clone or Download" on Github and copy the link.

2. Open RStudio, and go to File > New Project > Version Control > Git, and paste in the link you just copied. Under "Create Project as Subdirectory of", browse and select a folder where you want the course materials to go.

3. Press "Create Project". This will create a folder called 2022 in the folder you selected in step 2.

4. Now, you can open this project using the projects tab in the upper right of RStudio, or going to File > Open Project and then navigating to the 2022 folder and opening the .Rproj file.

If you already cloned the repository outside of RStudio (e.g. using Git Bash), you can associate the directory that was created in that step with RStudio. In RStudio, go to File > New Project > Existing Directory, and then navigate / click on the 2022 folder. Then click "Create Project". Then you can follow step 4 above to open the project when you launch RStudio. You can read more about RStudio projects here: https://support.rstudio.com/hc/en-us/articles/200526207-Using-Projects

Updating Course Repo

Once you cloned the course repository and want to get updates, you must use git pull to get updates.

In RStudio, if you followed the instructions above, simply navigate to the Git tab and press the Pull button. In terminal / Git bash, use cd to navigate to the 2022 folder, then run git pull.

Taking Notes on Course Materials

If you wish to take notes and write in the course materials, you can save a copy of the file you want to take notes on with the filename containing notes. For example, if you want to take notes on the file tidyverse.Rmd, save it as tidyverse-notes.Rmd. Then, you can edit the tidyverse-notes.Rmd file. We have configured Git to ignore any files that contain notes in the filename, so any changes you make won't show up in Git. This will allow you to update the course repo without any issues.
