Actually, this is knitr (which rmarkdown Imports) at work.  There are options as to how knitr will handle multiple plots in a chunk as described in


(which include `fig.show="animate"' to create an animation based on multiple plots!)

So this applies to various filetypes in addition to *.Rmd (*.Rnw, for one).

Is there any way to mimic the behaviour of rmarkdown instead? I odn't understand babel or R enough to really even see how something like that could be implemented, but I'd appreciate some pointers.  Thank you!

Getting babel to handle this seamlessly would be a significant effort.

You can use ox-ravel (https://github.com/chasberry/orgmode-accessories.git) to export to *.Rmd and then render the result.  However, that does not have the interactivity of `org-babel-execute-src-block' and does not insert the graphics into the *.org file. 

I suppose that a function could be created to narrow to the src block, export it as *.Rmd to a buffer, run that buffer as the `text' arg of knitr::knit, then add links for the png's back to the *.org file. I haven't thought much about this - getting this to work in a simple case would not be too hard, but there may be a can of worms that this approach opens.
