In the code of my previous message
the barplot should be:
barplot(apply(sel[,-1],2,mean))
instead of
barplot(sel)
Sorry for the confusion.

Asunto: barplot as Trellis graphic

Dear list,
Is there any way of making barplots as a Trellis graphic?
Currently I do something like:
class <- unique(mydata[,1])
par(mfrow=c(3,3))
for(i in class){
sel <- mydata[mydata[,1]==i,]
barplot(sel)
title(i)
}
where class would take values between 1 and 9
and the first column of mydata would be the class.
But I'm looking for a nicer code and a nicer graphic
using the approach of the lattice package.
Thanks!
