[R] Plotting a 3D surface

[lawrence Perepolkin]

Hi 

Does R have a function or has someone written a function to draw a 3d
surface from a scatter plot of values using either ksmooth or locpoly. OR a
transform function a that merges x relation z and y relation z to (x,y)
relation z?  

I tried out scatterplot3d but it seems it would take a bit of work to get
scatterplot3d to draw a curved surface.
