i graph library: how can generates a fully connected graph from a similarity matrix
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 Dinesh
