The scatter3d was very impressive; in case other folks are following along, I should note that I had to do sudo apt-get install libglu1-mesa-dev in order to get rgl to install x11 properly, but after that, the animated interactive graphics were amazing, so thank you very much for introducing me to that. The akima package appears to be the best way to move forward on interpolating the data. I will try to use akima to make a slightly more detailed grid and then try to put the output into contour.
