Ben, The way I approach these things is using Github Classrooms and pre-configured Actions. Takes a bit of extra work to set up initially but saves so much time in the long run.
Otherwise, the "classical" solution would be to mandate that all files should have lowercase naming in your rubrics and dock points for violations 🙂 One could provide them with a script that checks that everything in the project folder follows the naming conventions. I am less convinced that a feasible solution can be found from within R itself.

They don't notice this because they're using a case-insensitive file system on MacOS, but it bites me when I try to run the code on my Linux system. I can of course tell them to be more careful, but: is there any kind of programmatic check for this that they could use when testing their code before submission? (Students are not super-technically savvy, so telling them to adjust the properties of their file systems, even if it's something that's possible, is not a realistic option; neither is telling them to use GitHub Actions to run checks elsewhere ...) I'm imagining (ideally) some kind of _CHECK_CASE_STRICTLY_ environment variable/options setting/etc., but I'd be interested in any creative solutions.
