AdjacencyFromEdgelist {dils} | R Documentation |
Given the adjacency matrix for a network return a data.frame listing all possible edges and the weights for each edge.
AdjacencyFromEdgelist(elist, check.full = TRUE)
elist |
data.frame, see 'Details' for formatting assumptions. |
check.full |
logical, if TRUE ensures that all possible edges are in the list exactly once; if FALSE it assumes this is true. |
This assumes that elist
is a data.frame with three
columns. Each row is an edge in the network. The first
column lists the node the edge is coming from, the second
column lists the node the edge is going to, and the third
column lists the weight of the edge.
list, containing an adjacency matrix and a vector of node ids identifying the rows and columns.
adjacency | The adjacency matrix for the network. The row indicates the node the edge is coming 'from', the column indicates the node the edge is going 'to', and the value in the adjacency matrix is the weight given to the edge. |
nodelist | The ids of the nodes in the same order as the the rows and columns of the adjacency matrix. |
