R help - Mar 2008 - smoothScatter

Hi, I have been trying to plot density plots using the example on: 
 
http://addictedtor.free.fr/graphiques/graphcode.php?graph=139
 
I used to use this function, but I cannot get any old code or even the example
to work.
 
library("geneplotter")
require("RColorBrewer")
  x1  <- matrix(rnorm(1e4), ncol=2)
  x2  <- matrix(rnorm(1e4, mean=3, sd=1.5), ncol=2)
  x   <- rbind(x1,x2)
  layout(matrix(1:4, ncol=2, byrow=TRUE))
  op <- par(mar=rep(2,4))
  smoothScatter(x, nrpoints=0)
  smoothScatter(x)
  smoothScatter(x, nrpoints=Inf,
                colramp=colorRampPalette(brewer.pal(9,"YlOrRd")),
                bandwidth=40)
  colors  <- densCols(x)
  plot(x, col=colors, pch=20)
par(op)

But I can't even get the example to work. I have installed geneplotter and
RColorBrewer, but I get the messages "

Error: could not find function "smoothScatter"
Error: could not find function "densCols"

I thought it was something to do with the version of R, but I've now tried
it in 2.0-2.6 and nothing works. Does anyone know how to install smoothScatter
and densCols separately?
Any ideas?
Cheers,
Tom

I just tried it and had no problem with that code.  Are you sure the
packages are installed correctly?  What does sessionInfo() say after you
got the error?

smoothScatter() _is_ in geneplotter, as is densCols().
