[R] how to set chart output size in rgl (surface3d)?

[Karl Brand]

Hi Mandy and esteemed R users,

I'm searching for the functions you used to produce the shaded bounding 
box (and axis for that matter) of the plot image* attached to your 
orginal post.

Would you or anyone else be patient enough to post an example of such 
code or point me to the relevant functions? I think my PCA would 
certainly appear a lot more '3d' with such a shaded box & axis.

tia,

Karl
