R help - Apr 2009 - changing Swaeve output settings for .pdf and .eps - is there a way?

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.
