pcds.ugraph is a package for construction and visualization of the underlying graphs based on
proximity catch digraphs and for computation of edge density of these graphs for testing spatial patterns.
The pcds.ugraph functions can be grouped as AS-PCD Functions, PE-PCD Functions,
and CS-PCD Functions.
Contains the functions used in AS-PCD construction and computation of edge density of the corresponding underlying and reflexivity graph.
Contains the functions used in PE-PCD construction and computation of edge density of the corresponding underlying and reflexivity graph.
Contains the functions used in CS-PCD construction and computation of edge density of the corresponding underlying and reflexivity graph.

The PCD families considered are Arc-Slice PCDs, Proportional-Edge PCDs and Central Similarity PCDs (ceyhan:Phd-thesis,ceyhan:arc-density-PE,ceyhan:arc-density-CS;textualpcds.ugraph).
The graph invariant used in testing spatial point data are the edge density of the underlying and reflexivity graphs of the PCDs (see ceyhan:stamet2016;textualpcds.ugraph).
The package also contains visualization tools for these graphs for 1D-3D vertices. The AS-PCD and CS-PCD related tools are provided for 1D and 2D data; PE-PCD related tools are provided for 1D-3D data.
