Error in FUN (X [[1L]], ...): input as.edgelist.sna must be adjacency matrix / array, Edgelist matrix, net or sparse matrix or a list of these
I am trying to learn a few basic features in Igraph. But I'm having trouble calculating the powers from a graph: see example below (I copied the following example from this site):
edges <- matrix (c (103, 86, 24, 103, 103, 2, 92, 103, 87, 103, 103, 101, 103, 44), ncol = 2, byrow = T)
g <- graph (as.vector (t (edges)))
I can calculate the degrees around the edges of the matrix: Degree (edges)  378 254 210 390 380 408 294 1230 1084
But I cannot calculate degrees from graph g:
I am getting the following error:
Error in FUN (X [[1L]], ...): Input as.edgelist.sna must be adjacency matrix / array, Edgelist matrix, net or sparse matrix or its list.
Does anyone know why I am getting this error?
