If you are just trying to find the best set of rotation values to view your surface then the rotate.wireframe function in the TeachingDemos package may help. Unfortunately it is not currently working out of the box (a parameter name was changed in the lattice functions, I will fix this for version 1.6 of TeachingDemos).
You can easily fix the problem and get it working by doing: > fix(rotate.wireframe) Then find the line that is currently (line number 31): wire.options$formula <- formula And change it to wire.options$x <- formula Then it should work for you.
