Include Image in Rmarkdown Template Without Having to Create a New Directory for Template

I'm building a beamer-presentation template for a Bayesian Statistics class I TA for. I would like to include our school logo on the front of the slides but would prefer to not have to create a new directory for each new presentation just for that one image.

Is there a way where I can retrieve the relative file path from within the package resources folder and have it reference that location in the LaTeX beamer template?

Or will I be stuck having to create a whole new directory for a single presentation?
