> data(volcano)
> z <- 2 * volcano # Exaggerate the relief
> x <- 10 * (1:nrow(z)) # 10 meter spacing (S to N)
> y <- 10 * (1:ncol(z)) # 10 meter spacing (E to W)
> ## Don't draw the grid lines : border = NA persp(x, y, z,
> theta = 135, phi = 30, col = "green3", scale = FALSE,
> ltheta = -120, shade = 0.75, border = NA, box = FALSE)
