No, not really strange.  

1) The function is called ess-insert-function-outline;
   [ Patrick had been asking about the corresponding *variable* 
     with name ess-function-outline ]

2) "C-c f" is not activated by default since a good Emacs
   package is not allowed to set any "C-c <character>" key
   settings  {they are reserved for user-private settings}.
   But I concluded from Patrick's e-mail that he had found the
   hacky function  (ess-add-MM-keys)   -- guess who MM is --
   and that he does {in his ~/.emacs equivalent}
   something similar to what we do here, namely
      (add-hook 'ess-mode-hook 'ess-add-MM-keys)

   For a while now, this is only equivalent to 
      (add-hook 'ess-mode-hook 
                '(lambda () 
	          (define-key ess-mode-map "\C-cf" 

Alternatively (to "C-c f"), you bind  ess-insert-function-outline
to one of your favorite functions keys or so.
