Normally I hate the device()+code+dev.off()+cat('\\includegraphics{})
trick. Let me show you how trivial this can be in knitr:
https://gist.github.com/2790922This example shows the real source code to the reader (device()+dev.off() makes no sense to them), and leaves all the dirty tricks behind the scene. That being said, Sweave can be regarded as a subset of knitr, so if you really want to play the old trick, you still can do it in knitr.
