Adding loess lines subsetting to each panel in lattice plot
Try reading ?panel.loess. There is no "subset" argument, so it is of course ignored. -- Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into it." -- Opus (aka Berkeley Breathed in his "Bloom County" comic strip ) On Fri, Aug 12, 2016 at 9:10 AM, Juan Perez via R-help

Hello, I've created an xyplot and I want to add a loess line for x (Age) <=40 and another for values >40. In a way it is similar to this https://stat.ethz.ch/pipermail/r-help/2009-May/390502.html but still not succcessful. This is my try: xyplot(MOE~Age|Species, groups=Site, panel = function(x, y, groups=groups,...) { panel.xyplot(x, y, groups=groups,...) panel.loess(x,y,subset = x <= 40, col="black") panel.loess(x,y,subset = x >40, col="red") }) When I run the code it "works" but it plots the loess line for all the data, without subsetting.Any suggestion?
