That is what I see when I do this:
\begin{center}
<<fig=TRUE, echo=TRUE>>=
mydataframe <- data.frame(a=1:10,
b=rnorm(10),
c=rnorm(10))
pairs(mydataframe)

Sweave-manual.pdf gives the following code chunk
<<results=tex,echo=FALSE>>=
for(i in 1:4){
file=paste("myfile", i, ".eps", sep="")
postscript(file=file, paper="special", width=6, height=6)
plot(rnorm(100)+i)
dev.off()
cat("\\includegraphics{", file, "}\n\n", sep="")
}

This could obviously be adapted to my centering problem, but is it the
simplest way? It seems complicated compared with just pairs(mydataframe).
Also, Sweave will normally make both postscript and pdf plots, but this
would involve further complication in the code. I'm sure it's completely
standard to produce two copies of graphics, one a pdf and one an eps, but
it's another obstacle in my way when I want to get on with writing the
program and its latex description.
Thanks
David
