Yes. Sorry I had assumed that this was implicit, but I had misread Stevens
email. He said "especially if you are windoze".

Well, finding all the versions of R is going to be heuristic, so there is
nothing to stop you from doing both. I would suggest the following:

1) Check a variable set by the user -- they can always override things. 
2) Check c:/Program Files as this is the canonical and default location for
   storing programs on windows. 
3) Check the path. 

Then the user with d:/R could either set a variable, or add R to the path,
while the user who just accepted the defaults would have it work

In general, these days I try and stick with system defaults where ever
possible, at least for stuff not under my control. Even miktex and emacs are
in c:/Program Files now.

I didn't although emacs did:-)

User-Agent: Gnus/5.11 (Gnus v5.11) Emacs/22.0.990 (windows-nt)

I'm using Emacs from Emacs W32, on XP, latest R.

  MM> Your proposal should be amended, however, to

Ah, I think I have just worked out what was going wrong. The load-file-name
form should be returning true for me also. I am guessing here, but I guess
that I did eval-buffer while in ess-site.el. 

  --> I'm trying your suggestion

  PL> Second:

  MM> Once we know more about your setup (OS version, Emacs version, R version

Given above. 

  PL> Third:

  PL> Reading through the R tutorial, I have realised that I know almost know
  PL> statistics. Suggestions welcome....

  MM> The book by Peter Dalgaard, or another one from
  MM>    http://www.r-project.org/doc/bib/R-books.html

Thanks! Will do.
