I use R to plot data, and like to include information about the plot in the
caption. I do this by combining two named SRC blocks--one for the image, and one
for the caption--and then put their #+RESULTS: together. The caption is the
tricky bit; I use R to print a string that starts with #+CAPTION:, shown in the
exmaple below. While this works, I've wondered if there is a more elegant way to
do this. How do others do this?

Kind Regards,
Mike Gauland

#+NAME: image
#+HEADER: :session
#+HEADER: :results graphics
#+HEADER: :exports results
#+HEADER: :file (org-babel-temp-file "./figure-" ".pdf")
x <- rnorm(100)

#+NAME: caption
#+HEADER: :session
#+HEADER: :results raw
#+HEADER: :exports results
print(paste("#+CAPTION: The mean value is ",
            format(mean(x), digits=3),
	    ".", sep=""));

#+RESULTS: caption
#+RESULTS: image
