1 Download and install R

R is the data analysis program we will use: https://cran.rstudio.com/
Click on Download R for [insert your operating system]. Then choose the latest release. If anything should be unclear, here are more detailed instructions:
- Windows: click on base, then Download R-4.4.2 for Windows, then install.
- For macOS 11 & higher: click on R-4.4.2-arm64.pkg, for earlier versions: R-4.4.2-x86_64.pkg, then install
- Ubuntu: follow the provided instructions (copy each code line into your Bash Terminal (=Console) & press enter, enter your Laptop log in password when prompted.

Rstudio is the visual interface: https://posit.co/download/rstudio-desktop/
Choose your operating system (Windows, MacOS etc)
Install the most recent release.
- for Ubuntu: make sure the file is in your Downloads folder, then execute in your Terminal: sudo apt-get install ~/Downloads/rstudio-2024.12.0-467-amd64.deb
Open Rstudio to see if it worked.
If you have trouble installing, write to me at metzler[at]csh.ac.at latest before January 30 noon.

Under the Tools menu, go to Global Options… and uncheck the box that says Restore .RData into workspace at startup, and set this to Never.
This ensures you always start with a clear workspace, instead of loading data from your last coding session.
