R help - Mar 2008 - order the plots using lattice

Dear all,

I am running something similar to this short example:

library("lattice")
library("geneplotter")

X=matrix(cbind(1:100,100:1,c(1:50,50:1)),ncol=3)
Y=matrix(cbind(1:100,1:100,1:100),ncol=3)
names=1:3

dummy.df = data.frame(names = factor(names, levels = names),
  x = seq_along(names),
  y = seq_along(names))   

xyplot(y ~ x | names, dummy.df,
      xlim = c(1,100),
      ylim = c(1,100),
       panel = function(x, y, ...) {
         x <- X[,x]
         y <- Y[,y]
         panel.smoothScatter(x, y ,...)
       },       
       layout = c(2, 2, 1),
       strip = function(..., bg) strip.default(..., bg ="#cce6ff"))

In the output, the first plot is represented in the bottom left corner, I would
like the plots to be drawn from the top left corner but I cannot find in the
Lattice help, the argument to set to do that. I have tried to play with the
index.cond but depending on my number of plots to draw, it does not always work
properly in an automated script. Does anyone knows a trick to start drawing the
plots from the top left corner?

Thanks in advance for your help,
Audrey

IIRC, it's as.table = TRUE

Look through the help page for xyplot.
