Delaunay4Points

[1:n,1:3] matrix containing the BMKey, X and Y coordinates of the n, BestMatches NEED NOT BE UNIQUE, however, there is an edge in the Deaunay between duplicate points!

Points

OPTIONAL, logical, indicating if BM's are on a toroid grid. Default is True

IsToroid

OPTIONAL, A vector of length 2, containing the number of lines and columns of the Grid

Grid

PlotIt

Calculates the adjacency matrix of the delaunay graph for BestMatches (BMs) in tiled form if BestMatches are located on a toroid grid

Delaunay

A clustering approach for every projection method based on the generalized  U*-matrix visualization of a topographic map is made available here. The number of clusters and the cluster structure can be estimated by counting the valleys in a topographic map. If the number of clusters and the clustering method are chosen correctly, then the clusters will be well separated by mountains in the visualization. Most projection methods are wrappers for already available methods in R. However, the neighbor retrieval visualizer (NeRV) is based on C++ source code of the 'dredviz' software package and the Curvilinear Component Analysis (CCA) is translated from 'MATLAB' ('SOM Toolbox' 2.0) to R.
