R help - Jun 2012 - Changing strip text

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

Convert your Treat variable to a factor with appropriate
levels before plotting or (less desirable) use
as.factor(Treat) in place of Treat.

A couple of bits of advice for future posts:
1. We don't have your data, so either provide relevant
    information about it ( str() is useful) or, if
    possible, illustrate your problem with a built-in
    dataset. Or make up some data to illustrate the
    problem.

2. Excise extraneous information from your code;
    here we don't need your ylab, as.table, groups,
    type, auto.key.

Hi Julie

Try

strip.custom(factor.levels = paste("Treat",
c("0","2","4","8","16"), sep =
" ")
i.e
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) ),
                      strip=strip.custom(factor.levels = 
paste("Treat",
c("0","2","4","8","16"), sep =
" "),par.strip.text =
list(cex = 0.85) )
                 )

Should work but without an example ...
I have added par.strip.text in case the size is not right for you as 
an example for future use
