ccoeff {gRapHD} | R Documentation |
Returns the clustering coefficients of the nodes in a graph.
ccoeff(model=NULL,edges=NULL,p=NULL)
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. |
p |
number of vertices. If NULL , the p=max(edges) . |
The clustering coefficient is given by C_i=2*e_i/(k_i*(k_i-1))
, where
k_i
is the number of neighbours the vertex i
has, and e_i
is the number of edges between the neighbours of i
.
A vector with length p
with the clustering coefficient of each vertex.
