[R] draw piecharts or histograms at the points of a scatterplot

[rhelp at numberland.de]

Hi,

I?m fairly new to R and have a problem mentioned in the subject ...

I want to draw a scatterplot in 3d - either with scatterplot3d or - 
preferably - with the rgl package - but instead of points or text 
(text3d command of rgl) I would like to draw either histograms or pie 
charts to visualize further properties of the objects.

Is there a way to do this?

Many thanks in advance
