Using igraph: community membership of components built by decompose.graph()
...using decompose.graph(), community
detection functions from igraph and lapply().
I have an igraph object G with vertex attribute "label" and edge
attribute "weight". I want to calculate community
memberships using different functions from igraph, for simplicity let
it be "walktrap.community".
This graph is not connected, that is why I decided to decompose it
into connected components and run
"walktrap.community" on each component, and afterwards add a
community membership vertex attribute to the
original graph G.
I am doing currently the following

Clustering algorithms don't find obvious clusters
I have a directed graph which is represented as a matrix on the form
0 4 0 1
6 0 0 0
0 1 0 5
0 0 4 0
Each row correspond to an author (A, B, C, D) and the values says how many
times this author have cited the other authors. Hence the first row says
that author A have cited author B four times and author D one time. Thus the
matrix represents two groups of authors: (A,B) and (C,D) who cites
