 Thank you for the information and explanation. It seems that the problem
 comes from the windows shell.

 I try the following :  I explicitely told emacs to use bash
 with the following instructions :
 (setq explicit-shell-file-name C:/msys/1.0/bin/bash.exe)
 (setq shell-file-name explicit-shell-file-name)

 It works with bash.

 Thanks for that, I've stored your solution in the org-babel development repo
 with a view to modifying our code so that these probloems are minimised in
 the future, and we'll also make sure the documentation addresses this.

I'm a Windows user *and* an Ubuntu user for years, now, with one single common
`.emacs' file for both OS.

Therefore, I'll show you what I have in my `.emacs':

--8---cut here---start-8---
;;*** [ 41.1 Single Shell

;; for single shell commands
(setq shell-file-name bash)  ;; must be in the `PATH' (Windows users)


;;*** [ 41.2 Interactive Shell

;; for the interactive (sub)shell
(setq explicit-shell-file-name shell-file-name)
--8---cut here---end---8---

Almost the same, except the order (not important) and the fact that bash is
written in its simplest form: no hard-coded path, and no `.exe' suffix, so
that it works for both Win32 and Linux.

The only thing to do, for Windows users, is ensure that `bash.exe' (generally
located in `C:\cygwin\bin') is in the Windows PATH environment variable.

I would advice keeping such a construct, instead of full paths.

Best regards,
  Seb

 #+srcname:trial
 #+begin_src R :session org-babel-R-session
c(4,5,6,7,8,9)
 #+end_src

The session way works too.

Thank you.
