[R] Lattice xyplot help please.

[Felix Andrews]

Haoda,

You need to pass the 'subscripts' argument in your panel function on
to panel.xyplot(): panel.xyplot(x, y, subscripts, ...)

I think you want something like
pvalue[packet.number()]
and not
pvalue[subscripts]
(which values of TRT do the pvalues correspond to?)

By the way, it is best to provide your data as the output of dput().
That way we can just copy and paste it into R.
