[R] greek letters in rgl plot3d

[james.foadi at diamond.ac.uk]

Dear RGL experts,
I haven't been able to add greek letters to my rgl plot3d.
I have tried "expression" with no success.

Here is the interested bit:

> library(rgl)
> cb <- cube3d()
> plot3d(cb,xlab=expression(alpha),ylab="",zlab="",box=FALSE,alpha=0.5)

The expression(alpha) appears as "alpha", rather than as a greek symbol.
I suspect greek and mathematical symbols in general can be added to a plot3d
in rgl. Is that true?
