[R] how to plot three dimension data to filled contour plot or surface plot in R Ask Question

[Jeff Newmiller]

Ggplot does not do xyz. Look at package lattice or package rgl instead.

>I googled many surface and contour codes but I still not find some code for three dimension data yet. How to do that in R? Say, x is r1dn, y is r2dn, z is tdn, what about the three dimension data? Does ggplot can plot three dimension filled contour or surface plot? Or another alternative solutions?
