Details

type=1 produce graphs biplot. type=2 produce graphs triplot, the components are normalizad in scale 0-1. type=3 produce graphs on a 2d point set that are all subgraphs of the Delaunay triangulation. The Gabriel graph is a subgraph of the delaunay triangulation and has the relative neighbor graph as a sub-graph. help(graphneigh) package=spdep
