R help - May 2009 - How to turn the xyplot graphics upside-down?

Hi everyone,

I'm learning to use R. The below script works well, but i want to turn the
y-axis and the graphics upside-down, how should i do? Appreciate if any
tips!

xyplot(P3+PZ+P4+C3+CZ+C4+F3+FZ+F4~Time,groups=Cond,data=data,type="l",auto.key=list(space="top",points=FALSE,lines=TRUE),layout=c(3,3))

Your example isn't reproducible (i.e. we don't have the data), so
can't be
sure,
but try giving an explicit "ylim" argument with low and high limits
reversed.
For example:
> d <- data.frame(x=runif(100),y=runif(100))
> xyplot(y~x,data=d)
> xyplot(y~x,data=d,ylim=c(1,0))
or perhaps
> xyplot(y~x,data=d,ylim=rev(range(d$y)))
