To my eye, this seemed to be exactly what you have. But using hexl-mode, I 
see I have three blanks between ':session' and ':results', and two of 
them show up in '(:session\ \ )'. Using:


#+BEGIN_SRC R :session   :results output
xyz
#+END_SRC

  I get:

("R" "xyz
" ((:colname-names) (:rowname-names) (:result-params "output" "replace") 
(:result-type . output) (:comments . "") (:shebang . "") (:cache . "no") 
(:noweb . "no") (:tangle . "no") (:exports . "code") (:results . "output 
replace") (:session\ \ ) ...) "" nil 0)

Deleting the extra blanks gives the same result you have.
