Dear Subscribers, I am using R for quite a while nowadays on Ubuntu 10.04 LTS. I a using R for doing my statistics. Furthermore I am using it as a tool to generate the graphics for my publications. I am currently working on a project which involves nls-fits of three dimensional surfaces such as ellipsoids or even more complex. I have been searching R help and the manuals for a possibility to plot these surfaces. Is there any package in R that allows plotting something like this: http://uwwo.in-chemnitz.de/R-Problem/tsai-wu-principal-strain.pdf This plot was generated using Mathematicas ContourPlot3D function. I would love to be able to plot this in R. However, I could not find something which could this. Thanks a million for the help! Uwe -- Uwe Wolfram Dipl.-Ing.

You might want to also look at misc3d, which can compute 3d contours to be plotted by rgl (or other graphics systems). Duncan Murdoch
