I got quite used to just specififying in the header:

   // -*- mode: C++; c-indent-level: 4; c-basic-offset: 4; tab-width: 8 -*-

which means indent by four, offset by four (whatever that does) and use
regular 8 char tabs.  Otherwise I just emacs default values -- and for R I
follow what's in one of the manuals (R Internals?)

That would similar to what I have, albeit with default 'scheme' as "bsd"

Err, not even close. I understand as much Elisp as I understand Fortran. 

I think our 'non-policy policy' works so far. If we ever feel we need to
correct things, there is alsways GNU indent (and a contributor to RPostgreSQL
actually used it to standardize matters).

I did run 'M-x untabify' on all RInside examples yesterday, though, so that
users get consistent views of the indents so matter what their tabs settings.
But generally the tabs-vs-spaces war is about as useful as the vi-emacs
debate. We emacs users simply know we're right ;-)
