I am trying to determine how to evaluate homogeneity of points in 
three-dimensional space.

In two-dimensional data, I have used functions available in the Spatial 
package
        and I've have looked into the spatstat package
        but, as far as I can tell, neither appears to handle 3-dimensional 
data.

Is there another version, package, or software that does the same type 
(G-function, etc.) of evaluation for 3-D data?

Thanks sincerely,
