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?
