That's one problem, which clearly we should aim to resolve.

The REPL is not in itself for having things sent to from .R files.  The
first step is to simply type in things like "1+1" to the slime repl --
does that work?  (It should print 2, probably in red, and the resulting
output should have mouse actions associated with it).

To get stuff in .R files active, you will probably need manually to turn
slime-mode on for those buffers with M-x slime-mode RET.  Once that is
done, C-c C-c in a function definition should flash up that function
region with a temporary yellow highlight, and give an informative
message (hopefully "Compilation finished.") in the minibuffer.  Those
functions should then be defined in the current R session, and can be
called in the slime repl.
