UbigraphID-class: Identifiers for Ubigraph vertices and edges
In omegahat/RUbigraph: Interface to Ubigraph server via XML-RPC

Description Objects from the Class Slots Extends Methods Author(s) References See Also Examples

Objects in a Ubigraph display are identified by a unique identifier which is an integer. These classes represent such an identifier and also identify the type of object it identifies, i.e. a vertex or edge.

Objects of these classes are typically obtained via calls to newVertex and newEdge.

.Data:: these are (currently) simple scalar integers

Class "integer", from data part. Class "vector", by class "integer", distance 2. Class "numeric", by class "integer", distance 2. Class "data.frameRowLabels", by class "integer", distance 2.
