You can use the following *after* the \begin{document} directive:

The above is the default. Reset it to what you would like.
Note, as per that manual page, that the Sweave options 'height'
and 'width'
affect the size of the PDF and EPS files created, but it is the
above
command that controls the size of the image in the document itself.
Could this information be incorporate into the RweaveLatex help page?
Concerning the sizes of graphs, it contains only the following
information:
"
width: numeric (6), width of figures in inches.
height: numeric (6), height of figures in inches.
"
Unfortunately this concise information can easily mislead into
believing that these two options affect the graphs dynamically
produced and included in the final .pdf file. It might help for these
two sentences to specify what figures they're affecting, and also to
include some info about "\setkeys{Gin}{width=0.8\textwidth}".
Thank you
Liviu
It would also be worthwhile to include the information that Frank
found on disabling the impact of this option, so that the use of the
width and height arguments do actually define the plot image
dimensions in the resultant document. Frank noted it here:
https://stat.ethz.ch/pipermail/r-help/2009-June/202757.html
The key content is:
Regarding the issue of preventing Sweave from issuing the Gin option
to set all graphics output to have a width of 0.8\textwidth, it's as
easy as using \usepackage[nogin]{Sweave} ...
After seeing Frank's reference, the only way that one would
otherwise note it is to read Sweave.sty directly.
In my Sweave template .Rnw file, I am now actually using the [nogin]
option by default and set the plot dimensions for each figure chunk
as required.
Thanks Liviu for the above.
I have some proposed modifications to RweaveLatex.Rd which I include
here as a patch against the R-devel version of the file from svn. I
have added comments about the issue that Liviu raised, the use of the
[nogin] option and while I was at it, the [noae] option as well. There
are added to the 'details' section of the file.
I hope that this is helpful.
Regards,
Marc
