Dear all,I need to plot more than one surface in 3D using R. I tried with "persp" function, it produce only one surface. Could you please help me how can I do it? The X and Y axis are the same but I have Z1 and Z2. I want to have both results in one graph.
That's quite hard to do with persp because it needs to plot the segments in a certain order. You can do it in the rgl package using persp3d for the first surface, then persp3d( ..., add=TRUE) for the second. Note that persp3d and persp use slightly different conventions for how to specify colours; see ?persp3d for details.
