"no matter how long"?  ...
      as of "ten years ago" ? 
      	 ;-) ;-)

Anyway --- as nobody said so till now, and the vi-aficionados
have already raised the flag --- I'd like to remark that
the behaviour you desire has been the default behavior in ESS
(The "Emacs Speaks Statistics" plugin for Emacs,
 http://ess.r-project.org/ ) for many months now.

leaving R GUI for ESS  :-) :-)

For Windows, there's a very nice package of Emacs, bundled with
ESS (and AucTeX, *the* recommended LaTeX plugin for Emacs)
