I've just started a presentation using .Rpres, which is progressing really nicely, however, I'm a little confused as to why I have ended up with and
presentation.md and a
presentation.Rpres. I'm pretty sure they were both created immediately together, and both seem to stay in sync without me worrying about it.
The files look identical to me. Is there a file I should edit in preference, and the other feeds the preview? Is there one that I should commit to a git repo, and one that I shouldn't? Are there any differences I should understand that I (obviously) don't?
