This seems a question for the ESS-help list.
But you should be using Emacs customization these days: I have in my
.emacs
'(c-basic-offset 4)
'(c-default-style "bsd")
in custom-set-variables, and that is what the 'R Internals' manual
says for Emacs >= 21. (You can set that from the 'Customize Emacs'
menu item, Programming, Languages, C group.)

Those are recommendations for Emacs < 21.

It has been (long ago):
Alternatively, (for @acronym{GNU} Emacs 21 or later),
use customization to set the @code{c-default-style} to @code{"bsd"}
and @code{c-basic-offset} to @code{4}.)

Follow the above.
