Is there a way to change the default settings for Sweave figure output?
Sweave produces an .eps and a .pdf file as output (7x7 inch). Changing pdf
defaults changes the pdf() function output size but does not affect the pdf
size produced by Sweave.

pdf.options(height=3)
pdf("myfile.pdf")
	plot(1:10)
dev.off()

--> graphic height is 3 inch

<<>>=
pdf.options(height=3)
@
<<fig=TRUE, echo=TRUE>>=
	plot(1:10)
@

--> graphic height is 7 inch

The pdf() settings do not affect Sweave settings when producing a .pdf
graphic. How can I change the Sweave default settings to e.g. 3 inch?

TIA, Mark


PS. I posted a similar matter a week ago
(https://stat.ethz.ch/pipermail/r-help/2009-April/194352.html), but now I
think the question is much more precise.

Try setting the width and height options in the figure chunk:

<<fig1,echo=F,plot=T,pdf=T,width=5,height=3>>
    plot(1:10
@

To make a certain set of dimensions the defaults, use \SweaveOpts:

\SweaveOpts{width=5,height=3}

Also, even if you set the width of your plot to 3 inches, the plot will be
expanded to 80% of the textwidth by default.  To disable this (i.e you set
width=3 and your plot is actually 3 inches) use 

\usepackage[nogin]{Sweave}.
  
You will have to copy Sweave.sty to your local directory or to your texmf
directory for this to work.

You aren't changing it,
just using one of its options.

There are other ways to control the size:  it isn't always 80%.  I 
normally use something like
\setkeys{Gin}{width=0.75\textwidth} to control it.  You can reset this a 
number of times in
the same document.  (Read the LaTeX docs for graphicx to see the other 
keys that can be set.)

The reason I suggested using the nogin option is because the default
behavior has always seemed very unintuitive to me.  It seems that setting a
width and/or height parameter should be the only thing that needs to be done
to determine the size of the graphic.  I know this is documented but I think
it is overly confusing to a new user.   I know the first time I set width=3
and the plot still spanned 80% of the page threw me off.
