Nowadays, the recommended via is using "Customize Emacs" 
(from the [Options] menu, 
 either or directly by middle-mouse clicking on the
 underlined word "customize" in the help page you get after
 C-h v ess-dump-filename-template
)

which automagically produces something like

(custom-set-variables
  ;; custom-set-variables was added by Custom -- don't edit or cut/paste it!
  ;; Your init file should contain only one such instance.
 '(ess-dump-filename-template "%s.R")
)

in your ~/.emacs

nor does the modern "customize" way.

(yes, I know, since I've been doing that since ever ..)

    MatW> Any ideas?

It's a bug  {---> hence CC: to "ESS-bugs"} :

After adding the above, restarting Emacs, 
      M-x R 
      C-c C-d pi
then  C-h v ess-dump-filename-template
gives a *Help* buffer 
---------------------------------------------------------------
ess-dump-filename-template's value is "%s.S"
Local in buffer maechler.pi.R; global value is "maechler.%s.R"

...
...
---------------------------------------------------------------

Which shows that the variable's setting is not used everywhere
it should. Grepping in ess/lisp/*.el quickly reveals that
all the essd-*.el  files
explicitly construct  ess-dump-filename-template by prepending
(user-login-name) .... 
and post-pending the correct ending, namely  ess-suffix:  .R or
.S or ....

Ok, I'm working on fixing this.  I think a nice solution looks
possible.

As a workaround, do edit the ess/lisp/essd-<dialect>.el file
e.g., for R, it's  ess/lisp/essd-r.el file.
