Hello William,

Many thanks for reporting.

Ihor, many thanks for the suggestion. However I'm not sure it will work
here. The issue is that sometimes ESS has many ways of doing the same
thing so finding a middle ground is more challenging.

A possible configuration related to the point above for ESS is to do the
following

(setq ess-startup-directory nil)

(describe-variable  'ess-startup-directory)


which regardless of the value in the 'default-directory, will start the
R process in the current project directory

With the configuration above org-mode does not have any issues finding
the current directory. For instance

If I move following file test.org in the directory
/home/djj/Documents/projects/R. And run the code chunk I get.

#+begin_src R
  getwd()
#+end_src

#+RESULTS:
: /home/djj/Documents/projects/R


Moving it to /tmp/test/, I get
#+begin_src R
  getwd()
#+end_src

#+RESULTS:
: /tmp/test


Note also that you can force the R process to start in a particular
directory with the dir parameter.

#+begin_src R :dir ~/
  getwd()
#+end_src

#+RESULTS:
: /home/djj


Now on the org-mode side. This is becomes tricky because I don't know
what users expects. For now this issue is delegated to the ESS configuration.
Is the present state a satisfactory one? Please voice out your opinion.

Hope this help, 
Jeremie
