This is pretty much brute-force, but seems to work:
--8<---------------cut here---------------start------------->8---
#+startup: beamer
#+latex_class: beamer
#+options: toc:nil latex:t tex:t
#+latex_class_options: [presentation,bigger]
#+beamer_frame_level: 1
* plot
#+header: :width 8 :height 6
#+name: foo
#+begin_src R :exports results :results output graphics :file file.pdf
:pagecentre true
x <- c(1:10)
y <- x^2
plot(x,y)
#+end_src
#+LATEX: \begin{center}
#+RESULTS: foo
[[file:file.pdf]]
#+LATEX: \end{center}
--8<---------------cut here---------------end--------------->8---
