Follow up...

The following is working like a dream...

(defun ess-eval-function-or-paragraph-and-step-dan (vis)
  "Er..."
  (interactive "P")
  (ess-eval-function-or-paragraph-and-step vis)
  (previous-line 1)
  (ess-eval-line-and-step)
  )

(add-hook 'ess-mode-hook
      (lambda ()
        (local-set-key (kbd "C-c C-c")
               'ess-eval-function-or-paragraph-and-step-dan)
        )
      )


Except that the following function throws an error using C-c C-c (as 
bound above), whereas it is executed without error using C-c C-r over 
the whole region...


y <- function(x) {
  print(x)
}


However, this works...

y <- function(x) {print(x)}


Anything else (spread over more than one line) fails using my C-c C-c 
function. However, (of course) the original 
"ess-eval-function-or-paragraph-and-step" works fine.


Can anyone on the list help me to get the behavior I want without the 
above failure? I figure I can simply tweak the original function 
definition, but I am not sure how.


Cheers,

Dan.
