Changing the surface coloring (using lattice::wireframe)

问题:

I am using lattice::wireframe to create a surface. I need to change the coloring so that it depends on the x or y variable (instead of on z). How should this be done? The documentation says that the color is automatically chosen to depend on the height (e.g. z).

Thanks! Georgi

Use col.regions

wireframe(volcano, drape = TRUE,        aspect = c(61/87, 0.4),        light.source = c(10,0,10),         col.regions = colorRampPalette(c("blue", "pink"))(100))

As per your coment and with inspiration from @DWin who I am sure will do a better job here, perhaps with ?persp you can get closer to what you want.

> persp(x, y, z, theta = 135, phi = 30, col = colorRampPalette(c("blue", "pink"))(9500), scale = FALSE, +       ltheta = -120, shade = 0.75, border = NA, box = FALSE)
