I can't evaluate R code blocks in org files. For example the file with
contents:

--8<---------------cut here---------------start------------->8---
#+property: header-args:R :session R-foo

#+BEGIN_SRC R
  print(pi)
#+END_SRC
--8<---------------cut here---------------end--------------->8---

spawns an R session that reports:

--8<---------------cut here---------------start------------->8---
  Error: could not find function ".ess.eval"
--8<---------------cut here---------------end--------------->8---

and does not give me a result.
I am running ess-version: 14.09 and am invoking emacs as follows:

--8<---------------cut here---------------start------------->8---
#!/bin/sh

o=/usr/local/share/emacs/site-lisp/org
emacs -Q --eval="(progn
                  (add-to-list 'load-path \"$o\")
                  (require 'org)
                  (org-babel-do-load-languages
                   'org-babel-load-languages
                   '((R . t)))
                  (package-initialize)
                  (setq ess-ask-for-ess-directory 'nil
                        ess-directory \"~/R/\"))"
--8<---------------cut here---------------end--------------->8---
