Dear R users
I have a similarity matrix 100X100. I used this matrix as adjacency matrix
to generate igraph graph object. Its a fully connected graph. The similarity
score is the weight of the edge. Now I want to remove all possible lowest
scores (edges) but I want to get back a fully connected graph (dont want any
isolated vertex).How can I do it?
Also is there any possibility that I can remove the edges which dont pass a
threshold (below 70% similarity score).
I attached the similarity matrix.
I would appreciate the reply
Thanks in advance
