[R] lattice panel.abline use

Dear R-users, I am unsuccessful in trying to add an horizontal line to all graphs in the example below: library(lattice) val<-runif(15) x<-rep(seq(1:5),3) type<-c(rep("a",5), rep("b",5), rep("c",5)) xyplot(val ~ x | type, panel.abline(h=.6)) Any hints are appreciated. Best regards, ---Jean
