[R] Exporting an rgl graph

[Greg Snow]

The easiest approach may be to just install R onto a USB drive (flash/thumb/...) then when you go to your coworkers computer just run R from the USB drive and show the rgl plot.  I think there is also a tool to create an animation from rgl, it is not interactive, but you could e-mail a movie file that they could play to see the plot from many angles.
