[ESS] ESS + Cygwin Emacs

I don't understand your issue.  I have been using the cygwin shell
under GNU emacs for years.
There are at least two ways to do it.

1. Using cygwin directly with M-x shell
The incantation is to put this in your .emacs or your site-start.el

;;; shell on win95 to bash
;;; shell on windows to bash
(make-local-variable 'cygwin)
(make-local-variable 'cygwin-bin)
(make-local-variable 'cygwin-bash)
(setq cygwin (concat "c:/" "cygwin"))
(setq cygwin-bin (concat cygwin "/bin"))
(setq cygwin-bash (concat cygwin-bin "/bash.exe"))
(setenv "COMSPEC" cygwin-bash)
(setenv "SHELL" cygwin-bash)
(setq shell-file-name cygwin-bash)
(setenv "CVS_RSH" (concat cygwin-bin "/ssh.exe"))
(setenv "CYGWIN" "nodosfilewarning")

2. Using Rtools
Rtools includes much of cygwin.  Therefore from the MSDOS prompt, with
c:\Rtools\bin in the PATH

sh -i

3. You can probably skip cygwin and use something similar to my 1
(above) and make M-x shell start
the Rtools sh.  I haven't tried that.
