The :post header arg will allow this. 

In the examples below the first code line in the src block writes a file that 
is not subsequently overwritten.

#+name: file-output
#+begin_src emacs-lisp  
(org-babel-result-to-file *this*) 
#+end_src

#+begin_src R :results raw :post file-output()
cat("this is a test",file="testit.out")
"testit.out"
#+end_src

#+RESULTS:
[[file:testit.out]]


#+name: file-output2
#+begin_src emacs-lisp :var fname="xxx" 
(org-babel-result-to-file fname) 
#+end_src

#+begin_src R :results raw :post file-output2("testit2.out")
cat("this is a test",file="testit2.out")
#+end_src

#+RESULTS:
[[file:testit2.out]]
