Factor order in trellis plots --- summary

[David Parkhurst <parkhurs@imap.iu.edu>]

I asked:
I have a trellis plot with two columns (for N,Y in one factor) and five 
rows (for A,B,C,D,E in the other factor).  The rows come out with E on 
top and A on the bottom.  A reviewer of our paper objected to that, and 
wants us to have A on top, down to E at the bottom.
How can I make that happen?

Thanks to Sundar Dorai-Raj, Brad Biggerstaff, and Bill Dunlap for their 
replies.
Adding as.table=TRUE to the call worked fine.  I suspect that using 
levels=c("E","D","C","B","A") would have worked too, but I didn't try it.
Thanks again.
Dave
