I think these are good to go.

I checked several cases and all seemed to work as expected.

Some comments on this and your recent posts in this thread:

I see you took the suggestion to use (prin1-to-string value) on the 
'left-over' objects. With that stuff like :var x=[1 2 3] will work. :-)

The only failure I could trigger was with this block:

#+BEGIN_SRC R :session :var x=(org-export-get-backend 'latex)
x
#+END_SRC

which triggered 'Eval buffer', added a bunch of ^G's to my session log, 
and hung until I ran C-g (keyboard-quit).

When run with :session none, it works. I suspected the long string tripped 
over a limitation or bug in iESS-mode or comint-mode, but this runs:

#+BEGIN_SRC R :session :var x=(append (make-vector 10000 '(1 2)) '((1 2 3))) 
:results output
summary(x)
#+END_SRC

so I am not sure what gives.
