Thanks, it's looking good. Should we provide a renv.lock lockfile alongside it to ensure easier reproducibility?

I'm on the fence because we want to take into account updates to the packages we're comparing fundiversity to. But I'm afraid that updates to, e.g., rlang may be slightly annoying to diagnose and take into account if we want to re-run this script.

On the other hand, having renv.lock doesn't mean we have to use it. It can also serve as a session info to help in diagnosing what is preventing reproducibility.
