Use this if you are using igraph from R
The graphNEL class is defined in the
graph package, it is another
way to represent graphs.
graph_from_graphnel takes a graphNEL
graph and converts it to an igraph graph. It handles all
graph/vertex/edge attributes. If the graphNEL graph has a vertex
attribute called ‘
name’ it will be used as igraph vertex
name’ and the graphNEL vertex names will be
graph_from_graphnel(graphNEL, name = TRUE, weight = TRUE, unlist.attrs = TRUE)
The graphNEL graph.
Logical scalar, whether to add graphNEL vertex names as an
igraph vertex attribute called ‘
Logical scalar, whether to add graphNEL edge weights as an
igraph edge attribute called ‘
Logical scalar. graphNEL attribute query functions
return the values of the attributes in R lists, if this argument is
Because graphNEL graphs poorly support multiple edges, the edge attributes of the multiple edges are lost: they are all replaced by the attributes of the first of the multiple edges.
graph_from_graphnel returns an igraph graph object.
