[R] Trying to tile wireframe plots (using lattice package)

[Magnus Torfason]

Hi all,

I'm trying to print a number of wireframe plots (generated using the 
lattice package), and I want them to appear in a two-by two matrix along 
with some other (standard) plots. In other words I am trying to create a 
subplot or tiled plot that works for wireframes.

I've tried the methods discussed in:
http://tolstoy.newcastle.edu.au/R/e2/help/07/07/21238.html
but while they work for hist(), they don't work for wireframe().

I've also tried split.screen() and layout() - see below:

## Example of what I'm trying to do
library(lattice)
layout(matrix(c(1,2,3,4), 2, 2, byrow = TRUE))
# Top-left, as expected
plot(rnorm(100),rnorm(100))
# Top-right, as expected
plot(rnorm(100),rnorm(100))
# But the volcano fills the whole the device ...
wireframe(volcano)
## End of example

All has been to no avail up until now. I'd be grateful for any 
suggestions you may have.

Best,
Magnus

ps. If there is a way to do this using intermediate files (saving each 
plot as a PS file, and then tiling multiple PS files within the same 
device), that would be a totally acceptable solution for me as well.
