Hmm,  ess-inf.el has been containing -- for about 10.5 years it
seems:

(defun ess-eval-paragraph (vis)
  "Send the current paragraph to the inferior ESS process.
Prefix arg VIS toggles visibility of ess-code as for `ess-eval-region'."
  (interactive "P")
  (ess-force-buffer-current "Process to load into: ")
  (save-excursion
    (forward-paragraph)
    (let ((end (point)))
      (backward-paragraph)
      (ess-eval-region (point) end vis "Eval paragraph"))))

---------------------------------------------------------------    

but it is not (yet) bound to any key inside ESS,

as you propose here :

    Dan> (global-set-key (kbd "C-c C-c") 'ess-eval-paragraph)

Since I just see that  C-c C-c  is indeed unbound
in the *.R buffers,  we could adopt your proposed key binding
indeed.

What do others think about the proposed keybinding?

I could envisage an even smarter thing:

Bind C-c C-c to  ess-eval-paragraph-or-function
which does not yet exist, but which would

  - see if we are inside of a function definition;
  - if yes, call ess-eval-function
  - if  no, call ess-eval-paragraph

What do people think about this?
