Re : three-dimensional (volumetric) estimation from x,y,z
You may use the "geometry" package and the "convhulln" function. This will allow you to compute the convex hull volume of a set of points in a n-dimensional space. -- Guilhaumon Fran?ois Laboratoire "Ecosyst?mes Lagunaires" UMR 5119 cc 93 Bat 24 Universit?

interactive rotatable 3d scatterplot
I would like to create a 3d scatterplot that is interactive in the sense that I can spin it on its axes to better visualize some PCA results I have. What are the options in R? I've looked at RGL and perhaps it will suffice but it wasn't apparent from the documentation I found. Any demo scripts available for a package that will work? Mark -- Mark W.
