Hello,
I'm using org-mode to write R code and generate figures.
I have multiple files generated per code block, one png and one PDF.
This is so that I can display the graphic:
1) Inline in my org-mode buffer (png)
2) Upon export to HTML, viewable in the browser (png)
3) Included in a separate PDF, *not* from exporting my org-mode
file. For this, I would like a PDF version of the graphic to be
generated, and pdflatex can use it (pdf)
So, for points 1 and 2 above, no problem.
* Figure 1
Here is the first figure.
#+begin_src R :file figure1.png :width 960 :exports both :tangle fig1.R
plot(1,1)
#+end_src
For point 3, I use tangling to write the source code to a file. I
notice that the graphical code is wrapped by the export process by a
call to png() and dev.off().
My question, is there any facility to have the tangled code generate a
PDF, instead of PNG? I still need the png for goals 1 and 2, but the
pdf for goal 3. Anyone else have any other strategies for realizing all
3 of my goals?
I suppose one would be to define a named code block, and use the noweb
syntax:
Define the plot
#+srcname: fig-test
#+begin_src R
plot(1,1)
#+end_src
Tangle, but don't export
#+begin_src R :file figure1.pdf :exports none :tangle fig1.R :noweb yes
<<fig-test>>
#+end_src
Export, but don't tangle
#+begin_src R :file figure1.png :exports both :noweb yes
<<fig-test>>
#+end_src
This is not too bad, but maybe there's an alternative approach?
Thanks!
Erik Iverson
