I'm having a tough time with Docker while trying to run my R scripts. I have several folders for different experiments, each containing an R script. I've built a base R image, but when I launch a new container to run one of the experiments, it just hangs indefinitely without showing any errors. I need to stick to this base image and can't pre-install dependencies for each R script. What could be causing this issue?

I'm not sure I fully understand what 'rscript' is. I've been working with Docker and Compose since 2015, and this is the first time I’m hearing that term. Can someone clarify what rscript does?
Checking the logs of your container is a smart move! It might reveal hidden issues during startup. Also, you can run your R script interactively inside the container using `docker exec`. This way, you can see real-time output and diagnose if a specific segment of the script is causing the hang.
It sounds like there might be an issue with your entrypoint in the Docker setup. Try simplifying your commands—maybe replace your R script with a simple 'Hello, World!' first. If that doesn't work, try just using bash to echo 'Hello, World!' instead. It can help narrow down where the problem lies. If even that doesn't run, you might want to check the basics of your setup.
rscript is a part of the R programming language which allows you to execute R scripts from the command line. It’s super handy for running R code non-interactively!
