Please confirm that when you do

 M-x find-function RET org-babel-R-initiate-session RET

and scroll down 15 lines:

 M-1 M-5 <down>

you see something like this:

          (ess-wait-for-process
           (get-process (or ess-local-process-name
                            ess-current-process-name)))


If not, there is something broken in your setup.

If you do see that code, please do

 C-x d <return>


and verify that ob-R.el is older than ob-R.elc. If it is not older delete
ob-R.elc and restart.

Let us know how it goes either way.
