[R] Emacs & ESS under Windows

With the changes to the files, I was able to get this 
combination to work beautifully under Windows 2000.  I'm 
an utter novice with Emacs & ESS, but figured that since I 
wanted some "scripting" capabilities for R like those built 
into S-Plus 2000 (& 6.0 & earlier version SP4+), this might 
be one way to accomplish it.

Couple of questions:

1.  I've been working in the rgui and have a data directory 
defined for each project I'm working on.  It there a 
straightforward way to link the existing project directories 
(and the .Rdata files) with instances of emacs+ESS  or 
does this have to be done manually each time?   I don't 
want to reinvent the wheel.  I know that I can use:

 M-x ess-create-object-name-db

which seems to "import" the .RData file into the emacs\bin 
directory.  I'd like to keep the .RData file in its own project 
directory along with source code, text files, and various 
types of output files.  I'd also like to make certain the 
updates to data, code, etc stay in that project directory.  I 
didn't see any "quick and dirty" explanation for how to do 
this.  

2.  I noticed that under Emacs+ESS + R I am unable to 
tile the graphics window of R with the buffer window of 
Emacs.  Is there an Emacs (or ESS) sequence that 
forces the child windows to tile?

Thanks for your help.
