[R] changing the surface coloring (using lattice::wireframe)

[Smilyanov Georgi]

Hi all,

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
