Only read if you wanna use `school server`

Which Operating System do you use?

In all OS, you can use Terminal or cmd to connect, but I perfer not using it as a beginner.
Windows, depends on the version of your OS… but I strongly recommend using WSL2. Otherwise, you may use Putty. In addition, I think MobaXterm is a good choice to connect to the servers.
MacOS, well… you may just use terminal. I think even Screen Sharing client, a default software works. Alternative, you may use royal TSX.
Linux, I prefer Remmina.

log onto the (Linux) server, say, cpu151.math.private.uwaterloo.ca
cd to the directory where your code is located.
Type Rscript your_code.R to run the code.
You may want to use the nohup command to run the code in the background. For example, nohup Rscript your_code.R &
