I have used R in the past to generate two outputs for a given graph,
one PNG and one PDF from a source block in my Org file.

Then immediately under the source block I would put a commented out
file link so that Org's inline image display would show it to me. Then
I used the latex include command beneath to include the PDF for the
final output.

This let me preview and have high quality output.

Sample code:

#+BEGIN_SRC R :session *R-Buffer* :tangle myfile.R :exports none :results none silent :var basename="playerAging"
  doublePlot = function (base, plotFunc,
                         pngopts = c( width = 1024, height = 500 ),
                         pdfopts = c( width = 10, height = 7.5, paper =
                         'usr')
                         ) {

    # basename from org-babel
    myPng = paste(base,"png",sep=".")
    myPdf = paste(base,"pdf",sep=".")

    png(myPng, pngopts )
    plotFunc()
    dev.off()
    pdf(myPdf, pdfopts)
    plotFunc()
    dev.off()
  }

  doublePlot(base=basename, plotFunc = function() {
    plot(players$last_save,players$age,main="Player Age vs Last Login")
    grid(col="gray",lty=2)
  })
#+END_SRC

# [[file:playerAging.png]]

#+LATEX: \includegraphics[width=\textwidth]{playerAging.pdf}\newpage
