dear all,

I have some computation intense R-code that I want to run remotely on my
server, and, according to the org manual that should be possible with the
":dir" parameter. so I went on and tried the following (user/server masked):

#+BEGIN_SRC R :dir /xx@xxx:
  system("hostname")
#+END_SRC

when I execute it I get the error:

Tramp: Encoding region using function `base64-encode-region'...done
Tramp: Decoding region into remote file /ssh:xx@xxx
:/var/folders/ny/6kbb36310wz2kww8y8ctry600000gn/T/R-46345BQs...done
byte-code: Couldn't write region to
`/ssh:xx@xxx:/var/folders/ny/6kbb36310wz2kww8y8ctry600000gn/T/R-46345BQs',
decode using `base64 -d -i >%s' failed

apparently, this temp folder does not exist on the linux server, it is
actually the temp folder from my local machine.

I get the same error when I try to execute remote shell code, so it's not R
related.

I also tried to start a ssh session using "M-x ssh" and used the source
block

#+BEGIN_SRC R :exports both :session *ssh xxx*
system("hostname")
#+END_SRC

on the server it executes the command but it can not write the results:

> xxx
> Warning message:

I am using emacs 24.3 and Org-mode version 8.0.7 (release_8.0.7-384-g6fdc23)

I would be helpful for any suggestions how I could solve this problem.

thanks in advance
