R help - Sep 2010 - plotting convex hull for 3D

Dear all,

I have a 3 dimensional data and I need to plot a convex hull to it. I have
done it for 2 dimensional case using chull command in R. But I think it does
not work for more than 2 dimension.
Can anyone help me with this? Is there anyway to plot the convex hull for
more than 2 D case?

Thanks.

library(sos)
findFn("convex hull 3D")

 leads to the 'convhulln' function in the 'geometry' package;
the examples there show how to use the rgl package to plot
the results.
