removeNode: removeNode
In vjcitn/graph: graph: A package to handle graph data structures

Description Usage Arguments Details Value Author(s) See Also Examples

A function to remove a node from a graph. All edges to and from the node are also removed.

1	removeNode(node, object)

`node`	The label of the node to be removed.
`object`	The graph to remove the node from.

The specified node is removed from the graph as are all edges to and from that node. A new instance of the same class as object with the specified node(s) is returned.

Note, node can be a vector of labels, in which case all nodes are removed.

This is similar to subGraph.

A new instance of a graph of the same class as object but with all specified nodes removed.
