I'm trying to create a 5-panel xyplot with each strip labelled by treatment. The code is as follows:

xyplot(log(pfuml)~Transfer|Treat,groups=Pop,ylab="Log10 Pfu/ml",as.table=T,
		type="a",
		auto.key=
		list(space="right",points=F,lines=T))



I've tried:

strip=strip.custom(factor.levels=c("0","2","4","8","16")

But it's not working, I still only get "Treat" printed on each strip. Any ideas?

Thank you,

Julie
