[ESS] org-babel R source block gives invalid function: with-parsed-tramp-file-name

[Johannes Meisig]

Hi,

probably this is as much an org-mode as an ESS question. I get an error 
when executing an R source block with org-mode remotely

#+begin_src R :results graphics :file img.pdf :dir /user at host://home/user/
hist(rnorm(100))
#+end_src

This leads to invalid function: with-parsed-tramp-file-name. The error 
goes away only with :results output, but value or graphics will not 
work. Other languages do work

#+BEGIN_SRC sh :results value :file out.txt :dir /user at host://home/user/
hostname
#+END_SRC


Thanks for any advice on this,
Johannes
