Description Usage Arguments Value Functions Examples
These functions are wrappers around the various clustering functions provided
by igraph
. As with the other wrappers they automatically use the graph that
is being computed on, and otherwise passes on its arguments to the relevant
clustering function. The return value is always a numeric vector of group
memberships so that nodes or edges with the same number are part of the same
group. Grouping is predominantly made on nodes and currently the only
grouping of edges supported is biconnected components.

type 
The type of component to find. Either 
weights 
The weight of the edges to use for the calculation. Will be evaluated in the context of the edge data. 
directed 
Should direction of edges be used for the calculations 
node_weights 
The weight of the nodes to use for the calculation. Will be evaluated in the context of the node data. 
trials 
Number of times partition of the network should be attempted 
label 
The initial groups of the nodes. Will be evaluated in the context of the node data. 
fixed 
A logical vector determining which nodes should keep their initial groups. Will be evaluated in the context of the node data. 
steps 
The number of steps in the random walks 
options 
Settings passed on to

arguments passed on to 
a numeric vector with the membership for each node in the graph. The enumeration happens in order based on group size progressing from the largest to the smallest group
