impose points on lattice plot
R-help, I'm using the lattice package to plot 2 variables (vekt ~ aldur) conditioned to a third (kyn * 2 categories). I use the following: xyplot(vekt ~ aldur|kyn, , data = sexSu) I want to superimpose the average(vekt) by 'aldur' conditioned to kyn by using something like: xyplot(vekt~aldur|kyn, subset = aldur <= 12 , data = sexSu, panel = function(x, y) { panel.xyplot(x, y) panel.points(x,mean(y),col=2,cex=2 ) }) but th output...
