as_graphnel | R Documentation |
The graphNEL class is defined in the graph
package, it is another
way to represent graphs. These functions are provided to convert between
the igraph and the graphNEL objects.
as_graphnel(graph)
graph |
An igraph graph object. |
as_graphnel()
converts an igraph graph to a graphNEL graph. It
converts all graph/vertex/edge attributes. If the igraph graph has a
vertex attribute ‘name
’, then it will be used to assign
vertex names in the graphNEL graph. Otherwise numeric igraph vertex ids
will be used for this purpose.
as_graphnel()
returns a graphNEL graph object.
graph_from_graphnel()
for the other direction,
as_adj()
, graph_from_adjacency_matrix()
,
as_adj_list()
and graph.adjlist()
for
other graph representations.
Other conversion:
as.directed()
,
as.matrix.igraph()

as_adj_list()

## Undirected
## Not run:

## Directed
g3 <- make_star(10, mode = "in")
V(g3)$name <- letters[1:10]
GNEL2 <- as_graphnel(g3)
g4 <- graph_from_graphnel(GNEL2)
