[R] sorting Trellis panels

[Patrick Lorch]

Can anyone explain how to properly use index.cond?  I cannot include it 
in the xyplot command and get what I expect.  For example,

	plot<-xyplot(y ~ x | z, data)
# let's say z is a factor with six levels

gives a nice plot but I am unhappy with the order of panels.  I can get 
the order I want by

	plot$index.plot[[1]]<-c(1,6,4,3,2,5)

I cannot seem to get it with either

	plot<-xyplot(y ~ x | z, data,index.cond=list(order(c(1, ,6,4,3,2,5))))
or
	plot<-xyplot(y ~ x | z, data)
	plot
	update(plot,index.cond=list(order(c(1,6,4,3,2,5))))

I suspect it is some obvious misunderstanding of my use of 
list(order(...)).

Thanks for any help you can give,
	 -Pat
