grouped lattice plot with overall regression line
...ded. Could any expert help with this? I'd appreciate it greatly. The closest I could find was something like the following, which didn't work for me - anyways, it is supposed to draw by-group regression lines as well as the global one. So this is not exactly I need.
xyplot(T~A|speaker,data=spk0,layout=c(4,5),type='p',groups=fns),
panel=function(x,y){
panel.superpose(x,y)
panel.abline(lm(y~x))}),
panel.groups=function(x,y,lty){
panel.xyplot(x,y,lty=lty)
panel.abline(lm(y~x),lty=3)})
Thanks so much !!!
