R help - Aug 2011 - 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

I hope this helps:

xyplot(val ~ x | type,
       panel=function(...) {
           panel.xyplot(...)
           panel.abline(h=.6)
       })
