Hi
I am using following code to produce a xyplot for some longitudinal data. There
are 2 panels. It produced all longitudinal trajectories with mean profile. But
since the dataset it very large plot looks very messy. I want to show, say 10
randomly selected individual longitudinal trajectories together with mean
profile for entire dataset. Could any help me to alter the following code to do
this? or is there an alternative way?
Thanks in advance.
xyplot(Y~ time|status,groups=ID,data=heart,
type="l",lty=1, layout=c(2,1),main="",
panel = function (x, y, subscripts, groups, ...) {
panel.superpose (x, y, panel.groups = "panel.xyplot",subscripts,groups, ...)
panel.loess (x, y, col = "Red", lwd = 2,span=0.75, ...)
})
