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.

`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.
