[babel] Emitting both text & graphics output

[<Ken.Williams@thomsonreuters.com>]

Hi,

Suppose I have a source block like the following, which both 'print's some
text output and 'plot's to a graphics device:

------------------------------
#+begin_src R :file tp.png :exports both :results output graphics
dat <-  matrix(runif(12), 6, 2)
print(dat)
plot(dat)
#+end_src
------------------------------



I can't seem to get the print() output to display, either by exporting to
HTML or by simple evaluation of the code block.

'C-c C-c' results in the following 'results' section:

------------------------------
#+results:
[[file:tp.png]]
------------------------------



And 'C-c C-e b' results in HTML output like this:

------------------------------
<pre class="src src-R">dat <span style="color: #008b8b;">&lt;-</span>
matrix(runif(12), 6, 2)
print(dat)
plot(dat)
</pre>
<p>
<img src="tp.png"  alt="tp.png" />
</p>

------------------------------



Neither of those have the actual printed matrix output, which would be
something like this:

------------------------------
#+begin_src R :exports both :results output
dat <-  matrix(runif(12), 6, 2)
print(dat)
#+end_src

#+results:
:           [,1]      [,2]
: [1,] 0.3675202 0.1995134
: [2,] 0.9221087 0.1225686
: [3,] 0.6534830 0.6986238
: [4,] 0.3523151 0.1299406
: [5,] 0.7207582 0.5494278
: [6,] 0.3665547 0.6328452
------------------------------




Any clues?  Thanks.
