Hello,
This code builds a simple example of 2 wireframes :
require(lattice)
x <- c(1:10)
y <- c(1:10)
g <- expand.grid(x = 1:10, y = 1:10, gr = 1:2)
g$z <- c(as.vector(outer(x,y,"*")), rep(50,100))
wireframe(z ~ x * y, data = g, groups = gr, scales = list(arrows =
FALSE))
However, the intersection between the wireframes is not properly
drawn. Is there a way to fix this with lattice, or should I use
another package more suitable for this?
Thanks!
Guillaume
