neighbourhood {gRapHD} | R Documentation |
Finds the set of vertices with up to a given distance from a given vertex.
neighbourhood(model=NULL,edges=NULL,orig=NULL,rad=1)
model |
gRapHD object. |
edges |
matrix with 2 columns, each row representing one edge, and each column one of the vertices in the edge. Column 1 contains the vertex with lower index. |
orig |
central vertex. |
rad |
distance. |
Finds the set of vertices with up to a given distance from a given vertex.
Returns a list with:
subEdges |
matrix with 2 columns, each row representing one edge, and each column one of the vertices in the edge. Column 1 contains the vertex with lower index. |
v |
matrix with 2 columns, the first indicating the vertex index, and
the second the distance to the orig . |
