Why do You use i and k at the same time, is it nescecery?

You could try like this:

for (i in 2:7)

{

res

thank you so much for your response. but the problem here is that get.all.shortest.paths function is not working in for loop.

so can u suggest me better way of using this function in loop.

Hi,

I did some tests, and find a way to get what you want. First I suggest you to turn all matrixes into vectors and then try this:

file name is: gsp.R

======================

val=function(g,i)

{

get.shortest.paths(g, i)

}

val_all=function(g,i,prnodes)

{

get.all.shortest.paths(g, i,prnodes)

}

g

Also,

If you need to store the results You could use something like this:

=============

g

Thank you so much this is really a great help...
