Get entry ID for single or list of KEGGNode or KEGGedge object(s)

Description

The method extracts EntryIDs from KEGGNode-class or KEGGEdge-class object(s).

In case of KEGGEdge-class objects, the entryID of the nodes involved in the binary are returned as a vector in the order specified by the direction of the relation, that is, if the edge is defined as A->B, then the entryID returned from the edge equals to c(getEntryID(A), getEntryID(B)).

Methods

obj = "KEGGEdge"

Object of KEGGEdge-class

obj = "list"

A wrapper for list of KEGGNode-class or KEGGEdge-class objects
