babel: textual output and graphic results

babel: textual output and graphic results

[Eythan Weg]

Hi,

How could I effect the plot saved in a file and the output produced
shown in the buffer by using a single execution of R in the following
snippet?

#+begin_src R :results output :session 
print(seq(1,10))
plot(seq(1,10))
#+end_src

Thank you.
Eythan

Just add it as a cat() statement:

 #+begin_src R :results output :session
print(seq(1,10))
pdf("ThePlot.pdf")
plot(seq(1,10))
dev.off()
cat("[[./ThePlot.pdf]]")
#+end_src

True again.  It solves the problem by bypassing a babel's weakness, I think.

I would not say babel's weakness - rether a strength which result's in it's
simplicity and power.

Each code block can only return a single output type, so you will have
to split your code block into two, however (given that you are using
sessions) this should not affect the runtime behavior.  The following
will work...

#+begin_src R :results output :session
print(seq(1,10))
#+end_src

#+begin_src R :file example.png :session
plot(seq(1,10))
#+end_src

Is this property fundamental, or temporary?

This is intentional and will not be changed.

The alternative would introduce many complications without adding any
real new expressive power to code blocks.

Eythan,

This sounds similar to something I'd already done on Worg, ie: dual
format returns in R. The first example (RBabelExample) is really R
outputting to PNG for viewing inline in emacs with inline-images, and
PDF for inclusion into Latex.

Maybe you can adapt it to return your text, and graph separately.

http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-R.html

Enjoy.
