Re: [igraph] Shortest path matrix

Hi all,

I want the matrix not with numbers but with the vertex names as protein names. I already got the result of pair wise shortest path with its vertex names.
its class is igraph.vs. Is there any way to convert igraph.vs class in to matrix..??
a matrix like 

  [,1]                           [,2]     
[1,] "trpA" "tprB"    "trpC"  trpD"

That shows as result

  [,1]      [,2]     
[1,] String,2 String,2

Just tried the way you told. But it is giving the resultant matrix in form of 
    [,1]      [,2]     
[1,] Integer,3 Integer,3
[2,] Integer,3 Integer,3 in your example. This is not giving the result as 1 2 3  1 2 3  3 2 1  3 2 1 as this.

Yes, you need to index the matrix to see the actual result. Lists can contain pretty much any R object, so when your matrix has lists as cells, R cannot really print the contents, there is no guarantee that it would even fit to the screen.
