Short answer: almost none.

Long answer: what `org-babel-R-initite-session' and friends do.

This works great in R when I'm just doing math.  When I am working on plots, it would be nice to have them open up quickly either in emacs or in the standard x11 window that R session opened switch M-x R opens up.

It would be easier to just paste the plot command into the console and have it pop open the window... But that doesn't seem to work. Anyone know if I can tweak something to make that possible?

I sam really puzzled by this. Do you have an ECM that illustrates this?

Working interactively on my Mac (Quartz - X11 is the device), I routinely do what you describe - usually working from the src edit buffer - and the plots are displayed (and older plots are available via clover-left or some such).

If I had to guess, I'd say that you are opening an R session, but not using it. If you execute a src block, but it does not have a `:session' header, a new instance of R will create a plot file and then exit. If you look in the default directory, you would see `Rplots.pdf' or some such.

The only other thing that comes to mind is that you opened a device that is holding on to all your plots. Try `dev.cur()' in R immediately before and after you create a plot and see what the result is.
