Several types of summary are calculated and printed to the screen.
If type
equals "unit", a summary is given of all objects mapped
to that unit. In case type
equals "object", the summary
indicates the unit to which the object is mapped and shows other
objects mapped to it. For a type
of "smoothness", the function
returns the ratio of WCC values between neighbouring and
non-neighbouring units. Values larger than 1 show that neighbouring
units are "more alike" than non-neighbouring units. Type "quality"
does something similar: it compares all data objects and takes the
ratio of WCCs between objects mapped to the same unit and objects
mapped to different units.
