Ooooooh wow, I remember digging into R internals a while ago for something and seeing `sexp`, and only NOW am I connecting it to Lisp's SEXP!! That makes so much sense!

Does RData derive from LISP images? Because if so, that'd be quite the revelation to me.

RData only stores the environment of the session. It doesn't store the current search path (you need to reload libraries). I believe it's not a full binary image like LISP
