Hi James,

I ran all your code on a fresh R session (64 bit, OS X 10.6.0) and got no
errors. I suspect what Steve suggests is true:  your computer is running out
of memory. Have you tried running it on a 64 bit machine?

Here is my sessionInfo():

R version 2.11.0 (2010-04-22)
x86_64-apple-darwin9.8.0

locale:
[1] en_US.UTF-8/en_US.UTF-8/C/C/en_US.UTF-8/en_US.UTF-8

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base

loaded via a namespace (and not attached):
[1] grid_2.11.0    lattice_0.18-5 tools_2.11.0


HTH,
Jorge
