thank you so much for the very detailed indications which turned out to be a real help in ponting me to the right direction;
referring back to my previous questions there is something still open: 2- I'm in trouble with the point labels because I would like to rotate them by an angle of 90 degrees (and I did not find mention of anything like "angle" or "rot" to accomplish this task) panel.text(x, y, lab = mydata$name, cex = 0.6, pos=3, offset=0.5, "....here something to rotate labels") 3- I was referring to the error bar of each point (standard error of points); I think this could be accomplished by "arrows" but the following line is giving me an error panel.arrows(x=tv.avg-tv.erst, y=ped.avg-ped.erst, x1=tv.avg+tv.erst, y1=ped.avg+ped.erst, angle=90, code=3) thanks again for your great help in bootstrapping me to the lattice features maxbre -- View this message in context: http://r.789695.n4.nabble.com/lattice-panel-fine-control-tp3566347p3568424.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
