dear all, Is it possible to do some 3D Elliptic Fourier analysis with R? I've read <<Morphometrics with R (Use R)>>. There are several functions in the book like <efourier>, <iefourier>, and <NEF> to deal with the 2D closed outlines. Does anybody have any idea about how to deal with 3D outlines with R? Are there any known package, function, or publications about this? Thanks a lot! Yingqi ******************** Yingqi ZHANG Beijing P.O.
