I don't seem able to change the size of graphics in the PDF output.
#+begin_src R :file z.pdf :width 20 :height 20 :R-dev-args
bg="olivedrab", fg="hotpink"
plot(matrix(rnorm(100), ncol=2), type="l")
#+end_src
Using this example from an earlier post, regardless of how I change
the width and height settings the image in the PDF stays the same.
With this next example:
#+srcname:Boxplots Summary
#+begin_src R :session BirdData :file BoxplotSummary.pdf :exports both
boxplot(Wingcrd,Tarsus,Head,Wt,names=c("Wingcrd","Tarsus","Head","Wt"))
#+end_src
If I add height and width arguments the image stays the same size
regardless of settings, but the labels for the boxplots become tiny.
Am I missing some code somewhere that allows the graphs to be modified.
Thanks,
Graham

Hmm, this example is working for me. What about the axis annotation --
does that change size relative to the plot?

That's what one would see if you increase the width and height arguments
to pdf(). I.e. the labels get smaller relative to the plot size (unless
you also scale the labels size by using cex.lab or whatever) Is it
possible that the pdf output *is* changing size, but that your pdf
viewer is rescaling the images to the same size on your screen?

Dan/Torsten
Thanks, It seems to be a orgemode/babel/Latex issue.
If I view the pdf from within Emacs by double clicking on the link,
the size changes as expected, but if I compile the whole document as a
pdf the plots appear as small.
The error in the log is
! LaTeX Error: Cannot determine size of graphic in z.pdf (no BoundingBox).
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.283 \includegraphics[width=10em]{z.pdf}
The actual TEX file has
\includegraphics[width=10em]{BoxplotSummary.pdf}
\includegraphics[width=10em]{z.pdf}
So it seems to be ignoring the change in height and width commands for
z.pdf, and defaulting to 10em.

IGNORE everything in my last email.
The only relevant bit is
> \includegraphics[width=10em]{BoxplotSummary.pdf}
> \includegraphics[width=10em]{z.pdf}
>

If I then edit the [width=10em] bit in the tex file I can change the
size easily.
It just seems that babel isn't passing the changes made in the org
file onto the tex file.

A little progress here
#+srcname:Boxplots Summary
#+begin_src R :session BirdData :file BoxplotSummary.pdf :exports both
boxplot(Wingcrd,Tarsus,Head,Wt,names=c("Wingcrd","Tarsus","Head","Wt"))
#+end_src
#+resname: Boxplots
#+ATTR_LaTeX: width=10cm
[[file:BoxplotSummary.pdf]]
This gives me a plot 10cm wide, but in "addition" to the small plot.
Not sure I understand why I am getting two plots.

This works
#+srcname:Boxplots Summary
#+begin_src R :session BirdData :file BoxplotSummary.pdf :exports none
boxplot(Wingcrd,Tarsus,Head,Wt,names=c("Wingcrd","Tarsus","Head","Wt"))
#+end_src
#+resname: Boxplots
#+CAPTION: Trial boxplots with babel
#+LABEL: fig:trial boxplots
#+ATTR_LaTeX: width=10cm
[[file:BoxplotSummary.pdf]]
However, it needs :exports none
I actually want the code to still be present, but if I use :exports
code I get the both boxplots again :-(
I assume this is becasue the graphics are treated differently from
numerical code output.

OK, This was all to do with the ordering of the latex code
Below works, includes the R code, but only one plot of the expected size.
#+srcname:Boxplots Summary
#+begin_src R :session BirdData :file BoxplotSummary.pdf :exports both
boxplot(Wingcrd,Tarsus,Head,Wt,names=c("Wingcrd","Tarsus","Head","Wt"))
#+end_src
#+CAPTION: Trial boxplots with babel
#+LABEL: fig:trial boxplots
#+ATTR_LaTeX: width=10cm
#+resname: Boxplots
[[file:BoxplotSummary.pdf]]
I await for someone to tell me how it "should" be done :-)

Hi Graham,
I think your solution is sensible, and thanks for bringing up these
issues. Perhaps, as you suggest, we should be automatically setting
these attributes in the latex output; we'll get back to you on that.
Regarding the number of copies of the figure in the output, it should
work as follows:
Let's assume you have :exports both or :exports results.
Before running the export, do you have a link to the image *already* in
your org buffer?
If no, then you should just get one copy of the image.
If yes, then, if the link is positioned in such a way that it will get
replaced by the output (no intervening lines between end of source block
and results) then you should get one copy.
But if there are intervening lines between the source block and the
results, then you will get the original image, and a new one created by
the exporter which did not replace the original.
Thus I would do something like this, in which the pdf output is the same
regardless of whether the #+results line and link are in the buffer
before export, and which results in only one copy of the fig in either case.
------------------------------------------------------------------------
#+options toc:nil
#+title: R latex graphics
Text before figure.
#+CAPTION: Trial boxplots with babel
#+LABEL: fig:trial boxplots
#+ATTR_LaTeX: width=5cm
#+srcname:Boxplots Summary
#+begin_src R :session BirdData :file BoxplotSummary.pdf :exports both
Wingcrd <- rnorm(100, 20) ; Tarsus <- rnorm(100, 5) ;
Head <- rnorm(100, 3) ; Wt <- rnorm(100, 40)
boxplot(Wingcrd,Tarsus,Head,Wt,names=c("Wingcrd","Tarsus","Head","Wt"))
#+end_src
#+results: Boxplots
[[file:BoxplotSummary.pdf]]
Text after figure.

I would almost certainly already have the link as I have been making
minor changes and recompiling , what seems like hundreds of times
trying to sort out how to fix it

Thanks for this. It has to be said I am really excited about this
babel and R combination. I often do a few pages of R explanation on a
specific topic for students where I need to combine text and R output,
and this is a brilliant solution for this.
