[R] lattice code to plot columns over another variable

Hi, I've been struggling with a lattice visualiation. I have a
data.frame with 4 columns. What I'd like to have is a set of 3 panels.
Ecah panel will have the first column plotted against serial number
and then will superimpose the relevant column. My non-lattice version
is as follows:

x <- data.frame( ... )
par(mfrow=c(3,1))
for (i in 2:4) {
  plot(x[,1])
  points(x[,i])
}

Any suggestions as to how I could convert this to a lattice version
would be much appreciated

Thanks,
