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)))
