Hello: According to the annotation, the return value is as follows. Value: A length(vids) by length(vids) numeric matrix containing the similarity scores.But I tried to calculate the similarity in a subset of nodes(with m nodes) in my network(with totally n nodes). Instead of a m*m matrix, I got a m*n matrix. How could I get the value for the selected nodes(selected by their names)? I tried "similarity.dice()". It does return a m*m matrix, but similarity.invlogweighted doesn't. BTW, if a function return a matrix, then the value of matrix[i,j] is the result for the nodes with id "i" and "j", right? Thanks Best Quanwei
