[igraph] iGraphObjects

[Harun Pirim]

Dear All,

 

I have just registered to mailing list, and thanks for all inspring discussions.

 

I have couple of questions which may be really easy for you to answer:

 

1-) cGrph <- lapply(1:3, delete.edges(MST, c(which.max(edge.betweenness(MST))-1)))  I use that script to iteratively remove the most between 3 edges in MST(a tree) but this doesn’t work.

So how can end up with a forest removing the most between 3 edges using a loop structure?

 

2-) I have many subgraphs, I want to calculate the degree of vertices in each subgraph and hold them in a list to be able to compare with the values in another list.

 

I tried this code:

 

y <- lapply(0:4, function(i) paste(sgr, i, sep="") )

 

here sgr1 for example is a graph object, I was hoping exactly to get sgr1 object values when I write y[[2]], however this list gives confusing elements which is really different than sgr0, sgr1, sgr2, sgr3, sgr4.

 

Sgr1 is :

 

Vertices: 3

Edges: 3

Directed: FALSE

Edges:

                                           

[0] 'ERn_LNp_Nevins7'  -- 'ERn_LNn_Nevins26'

[1] 'ERn_LNp_Nevins7'  -- 'ERn_LNn_Nevins48'

[2] 'ERn_LNn_Nevins26' -- 'ERn_LNn_Nevins48'

 

 

 

Best Regards,
