[R] sort adjacency matrix_with data

[Ragia Ibrahim]

Hi again
the data represents a  directed graph  represented in a matrix

e.g 
library(igraph)
g <- forest.fire.game(10, fw.prob=0.3 , bw.factor=0.32/0.3, directed = TRUE)

m=get.adjacency(g , attr=NULL)
print(m)

----------
many thanks and pardon me for multiple posts
