R help - Mar 2011 - Sweave: include a multi-page-pdf plot

Hi,
I'm just starting out with Sweave, and I can't get a plot(linmod) to 
display all four plots:

<< bild >>x1 <- runif(100)
x2 <- rexp(100)
y <- 3 + 4*x1 + 5*x2 + rnorm(100)

mod <- lm(y~x1+x2)
plot(mod)
@

Some Text

<<fig=TRUE>><<bild>>
@

This plots only the first image of the four-page plot.lm() result.
I don't want to use par(mfrow=c(2,2)), but ideally I'd like to access 
each one of the four plots in a different section of my LaTeX-file.

Can you tell me how to do this?

Thanks in advance,
  Alex

If you want 4 separate pages, you need 4 separate plots.  You should 
change your code from plot(mod) to plot(mod, which=1), and then have 3 
more code chunks containing

plot(mod, which=n)

where n is a number from 2 to 6.  (The default is to use 2, 3, and 5.)
