# as_graphnel

From igraph v1.2.3
by Gabor Csardi

##### Convert igraph graphs to graphNEL objects from the graph package

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.

##### Usage

`as_graphnel(graph)`

##### Arguments

- graph
An igraph graph object.

##### Details

`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.

##### Value

`as_graphnel`

returns a graphNEL graph object.

##### See Also

`graph_from_graphnel`

for the other direction,
`as_adj`

, `graph_from_adjacency_matrix`

,
`as_adj_list`

and `graph.adjlist`

for
other graph representations.

##### Examples

```
# NOT RUN {
## Undirected
# }
# NOT RUN {
g <- make_ring(10)
V(g)$name <- letters[1:10]
GNEL <- as_graphnel(g)
g2 <- graph_from_graphnel(GNEL)
g2
## Directed
g3 <- make_star(10, mode="in")
V(g3)$name <- letters[1:10]
GNEL2 <- as_graphnel(g3)
g4 <- graph_from_graphnel(GNEL2)
g4
# }
```
