here is the data (fyi this is made-up data)
x = as.data.frame (
cbind(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),
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),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)))
names(x)=c("mortality","type","attend")
here is the image:

revised code with image:
x11(height=8,width=11)
xyplot ( mortality ~ factor(attend)|type,
panel=function(x,y){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))

i am trying to replicate the "red" mean lines on the xyplot graph
abline won't do it. llines may be able to do it, but i don't know how to
use/implement
