The usual graphics drivers don't support OpenGL, which rgl uses.  It 
would probably be possible to implement a standard R graphics device on 
an rgl canvas, but I don't know anyone who has done that.

You can always plot against negative x without labels, and add the 
labels for positive x later (using persp3d and axis3d).
