[ESS] New ESS user questions.

I've just started using ESS and so far it's wonderful. The only problem 
is session management. When I run R from a console, for each project I'm 
working on I have a script for invoking one or more R sessions in 
specific directories along with a text editor preset to open certain files.

The part I can't figure out is how to specify what the R working 
directory should be. I tried to set the default directory and launch R 
in my .emacs file as follows...

(setq ess-directory '"~/Documents/10_mydir")

...iESS launches an R session just fine but no matter what I set the 
directory to, R's working directory is always "~/Documents/". What am I 
doing wrong?

I suppose I could set the desired directory as an environment variable 
or write it to a temporary file and then have my .Rprofile read it and 
change directories accordingly, but that seems like reinventing the 
wheel if Emacs can do it for me.
