Not directly, But I used the following approach to include pdf as well
as jpeg ion a document.

You simply have to create your graph in R and then include a link in org
manually:

,----
| #+BEGIN_SRC R :results output :exports both
| png("testout.png")
| plot(1:10, 1:10)
| dev.off()
| x <- 1:10
| library(ascii)
| options(asciiType = "org")
| ascii(x)          
| #+END_SRC
| 
| 
| [[./testout.png]]
`----

you will get the code, result (output) and the graph (tested on export
to pdf).

Cheers,
