R help - Oct 2007 - Axis Location/Data view in scatterplot3d

All,

I constructed a fairly simple plot using the below and scatterplot3d. 
However, the axis locations in scatterplot3d seem to 'hide' quite a bit 
of the points in my graphic based on the viewing angle, hence not 
adhering to Tufte's rules.  I tried to determine if I could rotate the 
graph and relocate all three axis (origin (0, 0, 0))so they would be at 
the back left so the plotted points would slope down toward the viewer. 
  Using 'angle' and 'axis' did not get me any closer.  Does
anyone have
any suggestions?

TIA,
Bret

The plot3d() function in rgl allows manipulation of the viewpoint, and 
fairly flexible specification of the axes.
