Dear Bernd,

This is a problem relating to running R as an external shell process
under Windows. For the time-being, please use the :session header
argument to specify that evaluation is to take place in a persistent
emacs R session. Alternatively, you could use the following
configuration code to force R blocks to always use the specified session
(you can change the session name of course):

(setq org-babel-default-header-args:R '((:session . "*my-R-session*")))

Session-based evaluation is described briefly at

http://orgmode.org/worg/org-contrib/babel/org-babel.php#basic-functionality

Thanks for the report. We will investigate the issues with running R as
an external process under Windows.

Best wishes,

Dan
