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 with relative neighbor graph.

The relative neighbor graph is defined by the relation, x and y are neighbors if

d(x,y) <= min(max(d(x,z),d(y,z))| z in S)

where d() is the distance, S is the set of BIPLOT points and z is an arbitrary point in S.

Example output

     PLEASE NOTE:  The components "delsgs" and "summary" of the
 object returned by deldir() are now DATA FRAMES rather than
 matrices (as they were prior to release 0.0-18).
 See help("deldir").
 
     PLEASE NOTE: The process that deldir() uses for determining
 duplicated points has changed from that used in version
 0.0-9 of this package (and previously). See help("deldir").
