All,
I am wondering how one might add a reference line or plane to a cloud or wireframe plot. I have been unable to figure this out. Let's say I would like to draw a reference for some value of wt in the example below: cl <- 54.1 age <- 10:80 wt <- 25:160 sim <- expand.grid(age = age,wt = wt) sim$cl <- cl*(sim$wt/70)**0.412 * (sim$age/50)**0.152 library(lattice) print(cloud(cl~wt*age, data = sim)) Any thoughts you could provide are greatly appreciated. Thank you!
