I'm following up on my last post, just to have it in the record: I've 
boiled down the behavior to these two examples: output the results by 
value vs output.  R seems not to have anything to do with it.  Somehow 
the "by value" code is intervening.  I'll try to debug.

command line:
$ emacs -Q -eval '(setq load-path (cons 
"~/share/emacs/site-lisp/org-mode/lisp" load-path))' -eval "(require 
'ob-sh)" test.org

In the buffer:
*** by output
#+name: by-output
#+begin_src sh  :results output
  echo 987654321
#+end_src

#+RESULTS: by-output
: 987654321

*** by value
#+name: by-value
#+begin_src sh  :results value
  echo 987654321
#+end_src

#+RESULTS: by-value
: 987654321.0
