Emacs Environment Variables
This probably pertains more to Win32 Emacs than *nix based Emacs as the problems are likely to manifest in Windows where things land up in places where you least expect it. At least on *nix systems, the process of finding out which configuration files are read is straightforward from etc to the shell configuration files( .profile, .rc ), in that order.
On Windows, I have no idea where things are read and in what order. So how do we find out what are the values set for HOME, USER etc on Emacs?
M-x getenv will provide a prompt that lists all the set variables. It comes with completion, so one should be able to see the entire list of set variables that Emacs has read and is using. So, if you're wondering where the TEMP files are being stored,a M-x getenv RET TEMP would spit out the value stored by Emacs.
So, that's how one queries for the environment variables but how does one go about changing them?
We use M-x setenv to set the values for the session temporarily as in
Please note these changes do impact or change the OS set values but is limited to the current Emacs session. If you want to make those new values available for all future sessions, add something similar to your .emacs. For e.g. to set the TERM value, do
A good discussion on using the above information to selectively set certain values can be found on this gmane emacs thread.
The process-environment variable has the list of overridden environment variables for subprocesses to inherit launched from within Emacs. It would get modified by issuing a setenv command. The doc strings for getenv,setenv (by using C-h f ) has more information on their usage.

Emacs Speaks Statistics Tutorial
From the org-mode mailing list, here's a tutorial announcement and link to Emacs and ESS tutorial. You can find the slides and reference cards on ESS and a bit of org-mode for R users at the above site. And probably invite the author to come and give a talk. :-)
