Python works this way.  But babel R has a completely different *this*
value.  Consider the following example:

  #+BEGIN_SRC R :results output graphics :file line.png :dir /ipmuap02:/tmp
  plot(c(1,2,3))
  #+END_SRC

  #+RESULTS:
  [[file:/scp:ipmuap02:/tmp/line.png]]

*this* equals "[[file:/scp:ipmuap02:/tmp/line.png]]", but in babel
python *this* equals "line.png".

So I come up with

  #+name: localize
  #+BEGIN_SRC emacs-lisp :var file="" srcinfo=(org-babel-get-src-block-info)
    (let ((lang (car srcinfo)))
      (cond ((string= lang "python")
             (let* ((dir (cdr (assoc :dir (nth 2 srcinfo))))
                    (rfile (concat (file-name-as-directory dir) file))
                    (lfile (car (last (split-string rfile ":")))))
               (copy-file rfile lfile 1)
               lfile))
            ((string= lang "R")
             (let* ((rfile (substring file 7 -2))
                    (lfile (car (last (split-string rfile ":")))))
               (copy-file rfile lfile 1)
               (concat "[[file:" lfile "]]")))))
  #+END_SRC

But the result is a string rather than a file link:

  #+HEADER: :post localize(*this*)
  #+BEGIN_SRC R :results output graphics :file line.png :dir /ipmuap02:/tmp
  plot(c(1,2,3))
  #+END_SRC

  #+RESULTS:
  : [[file:/tmp/line.png]]

Any hints?

Yours,
Benda
