What you are describing is exactly what ESS is designed to make much
simpler...

So, you split Emacs to have 2 buffers, one with R and the other (or
many others) with source files).  In the next version of ESS, John
Fox's simple split screen will be available, along with toolbar
buttons for R, S-PLUS, and (hopefully) SAS.

C-c C-r to send it to R.

Or if it's within a function block, C-c C-f to send it to R

Or to send the current line, or buffer, or send line and step to the
next non-comment, and well...

C-c C-v object.to.get.help.on

Press "l" on the example code to evaluate one line and step to the
next.
