Re: [igraph] Shortest path matrix

Yes, create a matrix from a list, and then put the igraph results in it. R matrices can be lists, eg.

a <- list(1:3, 1:3, 3:1, 3:1)
matrix(a, 2, 2)

Hi gabor,
Thank you for response.
I have worked with it but it is just giving a vector. But i want  i want the matrix which display the shortest path sequences. Like if there are two nodes A and B and the shortest path between them is A C B. Then i want the matrix of displaying shortest path as a single matrix element with A C B. Is there any way to do this..??

You can convert an igraph.vs to vertex names with `as_ids`, and vertex ids with `as.vector`.

Are you using the 'shortest.paths' function? It returns a matrix

Hi ,
I am using igraph package for finding shortest paths between two nodes of graph. As my dataset is having biological information about Protein Protein Interaction. The names are of type string and those are the names of proteins. I have names of 11 proteins and i found the shortest path between all those 11 proteins pairwise. As a result of for loop i am getting the list of shortest paths and the vertex sequences as a class igraph.vs. I want to display this result in matrix of 11*11. How can i do this ?? Can any one help ??

Thanks
