Matrix

[lalagom]

Does the matrix always has to be square? I have this recurrent error when simulating extinctions:

web <- as.network(mat, bipartite = TRUE, directed = FALSE,

•               loops = FALSE,matrix.type = "incidence")
  

sp_1 <- SimulateExtinctions(Network = web, Order = 1:5,

•      Method = "Ordered", IS=0.7, NetworkType = "Mutualistic") [[1]]
  

Error in graph.adjacency.dense(adjmatrix, mode = mode, weighted = weighted, :
Adjacency matrices must be square.
