The following works for me:

--8<---------------cut here---------------start------------->8---
#+LATEX_HEADER: \usepackage{svg}

#+begin_src R :results  graphics output :exports both :file mtcars.svg :results none
library(ggplot2)
qplot(wt, mpg, data = mtcars)
#+end_src

#+BEGIN_LaTeX
\includesvg{mtcars}
#+END_LaTeX
--8<---------------cut here---------------end--------------->8---

The only problem is that I use minted to typeset code blocks and it
apparently does not know how to deal with R code blocks, so the code
block is not present in the PDF file. But the image is there. I attach
the resultant tex and pdf files.
