| gNode-class {graph} | R Documentation |
This is an implemention of a very general graph node class. It is patterned after the descriptions in GXL.
Objects can be created by calls of the form new("gNode", ...).
These are nodes of a graph and can have any number of attributes.
nodeID:"integer" a unique
integer identifier.nodeType:"character" the type
of node. Could be a factor. toEdges:"integer" A vector of
the edge identifiers corresponding to the edges pointing to that node. fromEdges:"integer" A vector
of the edge identifiers corresponding to the edges starting at
that node. edgeOrder:"integer" A vector
of edge identifiers indicating the order in which they would be
traversed (may also be used for rendering). label:"character" A label of
the node. Should be unique. signature(object = "gNode"): A method that
returns the edgeOrder for the named node.signature(object = "gNode"): A method that
returns the fromEdges. signature(object = "gNode"): A method that
assigns the fromEdgessignature(object = "gNode"):A method that
returns the node label. signature(object = "gNode"): A method that
returns the node identifier. signature(object = "gNode"): A method that
returns the node type. signature(object = "gNode"): A method that
returns the toEdges. signature(object = "gNode"): A method that
assigns the toEdges. R. Gentleman
