i am trying to replicate the following graph using xyplot : attach(x) plot ( jitter(type), mortality, pch=16, xlim = c(0.25, 3.75)) lines ( c(1-0.375,1.375) , c ( median(mortality[type==1]), median(mortality[type==1])), lwd=5,col=2) lines ( c(2-0.375,2.375) , c ( median(mortality[type==2]), median(mortality[type==2])), lwd=5,col=2) lines ( c(3-0.375,3.375) , c ( median(mortality[type==3]), median(mortality[type==3])), lwd=5,col=2) detach(x) in the above graph, i draw a median line for "mortality" (range from 5 to 35) by "type" (1,2 or 3). i now have an additional variable "attend" (0 or 1). within each panel (three panel, one for each "type"), i would like to draw the median "mortality" for each instance of "attend". i have been able to get as far as plotting everything but the median lines: x11(height=8,width=11) xyplot ( mortality ~ attend|type, panel=function(x,y,subscripts){panel.grid(lty=5); panel.xyplot(x,y,pch=16,jitter.x=TRUE,col=1)}, strip=strip.custom(which.given=1, bg="orange"),data =x,aspect=2:1,layout=c(3,1)) any suggestions on how to add the median lines of "mortality" for each instance of "attend" within each panel of "type"? thank you -- View this message in context: http://r.789695.n4.nabble.com/Drawing-a-line-in-xyplot-tp4538689p4538689.html Sent from the R help mailing list archive at Nabble.com.

Thank you David, the bwplot option does what I need: x11(height=8,width=11) bwplot ( mortality~ attend|type, pch=95,cex=5,col=2, par.settings=list( box.rectangle = list(col = "transparent"), box.umbrella = list(col = "transparent"), plot.symbol = list(col = "transparent") ), panel=function(x,y,...){ panel.grid(lty=5) panel.xyplot(x,y,pch=16,jitter.x=TRUE,col=1) panel.bwplot(x,y,...) }, data = x,aspect=2:1,layout=c(3,1)) However, I am interested in also learning how to do it in xyplot as well.

This can be simplified by using the layering abilities that Felix Andrews made available in latticeExtra. These are too little known. These pretty much make it unnecessary to resort to trellis.focus(), at least in such cases as this. These layering abilities are too little known: library(latticeExtra) x11(height=8,width=11) xdat = data.frame(mortality =c(5, 8,7,5,8,10,11,6,4,5,20,25,27,30,35,32,28,21,20,34,11,15,18,12,15,12,10,15,19,20), typec(1, 1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3), attend = c(1, 0,1,1,1,1,0,0,0,1,0,1,0,0,0,0,1,0,0,0,1,1,1,0,1,0,1,0,0,0)) gph <- xyplot ( mortality ~ attend|type, panel=function(x,y) { panel.grid(lty=5) panel.xyplot(x,y,pch=16,jitter.x=TRUE,col=1) for(i in 1:3) { panel.segments(x0=c(0.7, 1.7), x1=c(1.3, 2.3), y0=with(xdat, c(tapply(mortality[type==i], attend[type==i], median))), y1=with(xdat, c(tapply(mortality[type==i], attend[type==i], median))),col="red",lwd=4) } }, data = xdat, aspect=2:1,layout=c(3,1)) ## Now create a layer object that will add the further segments. addlayer <- layer(panel.segments(x0=1,y0=20,x1=1.2, y1=20), panel.segments(x0=2,y0=30,x1=2.2, y1=30)) gph+addlayer The code that produces the object gph would also be simpler and easier to follow if some relevant part was separated out into a separate layer.

i appreciate all the interest in my question, and thank you Elai for both of your suggestions, which work very well. Elai, your last code was particularly simple and helpful to generate the figure i was looking for. x11(height=8,width=11) par(lend=2) xdat = data.frame(mortality =c(5, 8,7,5,8,10,11,6,4,5,20,25,27,30,35,32,28,21,20,34,11,15,18,12,15,12,10,15,19,20), typec(1, 1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3), attend c(1, 0,1,1,1,1,0,0,0,1,0,1,0,0,0,0,1,0,0,0,1,1,1,0,1,0,1,0,0,0)) xyplot ( mortality ~ factor(attend)|type, panel=function(x,y) { panel.grid(lty=5) panel.xyplot(x,y,pch=16,jitter.x=TRUE,col=1) yy<- tapply(y,x,median) panel.segments(x0=c(0.7,1.7), x1=c(1.3,2.3), y0= yy , y1= yy , col="red",lwd=5) }, data = xdat, aspect=2:1,layout=c(3,1)) http://r.789695.n4.nabble.com/file/n4541912/trial.jpg as a side note, the par(lend=2) function did not square the ends of the lines for panel.segments in xyplot (i was trying to get square ends instead of round ends).

PS: The following shows possibilities that are available using latticeExtra layering: ## Best make type and attend factors xdat = data.frame(mortality =c(5, 8,7,5,8,10,11,6,4,5,20,25,27,30,35,32,28,21,20,34,11,15,18,12,15,12,10,15,19,20), typefactor(c(1, 1,1,1,1,1,1,1,1,1,2,2,2,2,2,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3)), attend = factor(c(1, 0,1,1,1,1,0,0,0,1,0,1,0,0,0,0,1,0,0,0,1,1,1,0,1,0,1,0,0,0))) gph <- xyplot (mortality ~ attend|type, pch=16, data = xdat, aspect=2:1,layout=c(3,1)) one4all <- layer(avy <- median(xdat$mortality), panel.segments(0.1, avy, 0.3, avy, col="red",lwd=4), panel.segments(0.7, avy, 1, avy, col="red",lwd=4)) medbytype <- layer(avy <- median(y), panel.segments(0.1, avy, 0.3, avy, col="red",lwd=4), panel.segments(0.7, avy, 1, avy, col="red",lwd=4)) interact <- layer(panel.average(x, y, fun=median, col='red', lwd=4)) Compare gph + one4all (shows overall median lines in all 3 panels) gph + medbytype (shows separate median lines for the separate panels) gph+interact (gives a form of interaction plot) NB x (if its values are used) and y are local to the individual panel NB also that layer() accepts a data argument. The following is an alternative way to calculate one4all: one4all <- layer(data=xdat, avy <- median(mortality), panel.segments(0.1, avy, 0.3, avy, col="red",lwd=4), panel.segments(0.7, avy, 1, avy, col="red", lwd=4)) John Maindonald.> This can be simplified by using the layering abilities that Felix Andrews > made available in latticeExtra.
