When executing your example below on my system both code blocks work as
shown below.

#+begin_src R :results output :exports results
  foo=matrix(1:2)
  foo
#+end_src

#+RESULTS:
:      [,1]
: [1,]    1
: [2,]    2

#+begin_src R :results output :exports results :session *R*
  foo=matrix(3:8)
  foo
#+end_src

#+RESULTS:
:      [,1]
: [1,]    3
: [2,]    4
: [3,]    5
: [4,]    6
: [5,]    7
: [6,]    8


If you are not using the latest version of Org-mode (from git) I would
suggesting updating to the Org-mode git HEAD which should hopefully fix
this issue.
