Cluster similarity matrix by graph community detection methods
cluster_by_igraph(mat,
method = c("fast_greedy",
"leading_eigen",
"louvain",
"walktrap"),
...)
mat |
The similarity matrix. |
method |
The community detection method. |
... |
Other arguments passed to the corresponding community detection function, see Details. |
The symmetric similarity matrix can be treated as an adjacency matrix and constructed as a graph/network with the similarity values as the weight of hte edges. Thus, clustering the similarity matrix can be treated as detecting clusters/modules/communities from the graph.
Four methods implemented in igraph package can be used here:
fast_greedy
uses cluster_fast_greedy
.
leading_eigen
uses cluster_leading_eigen
.
louvain
uses cluster_louvain
.
walktrap
uses cluster_walktrap
.
A vector of cluster labels (in numeric).
