We have 3-Dimensional MRI density recordings of tumor tissue and would like to have a measure of "patchiness", reflecting cluster size in the tissue.
For 2-D slices, correlogram from MASS works well. Does someone know of a packages that provides a 3-D generalization of this measure? Or any alternatives? I assume this is quite a common question in climate research.
