GOLeaves {GOstats} | R Documentation |
Given a GO graph this function returns the node labels for all leaves in the graph. A leaf is defined to be a node with only out-edges and no in-edges.
GOLeaves(inG)
inG |
An instance of a GO graph. |
All nodes in inG
are inspected for in-edges and those with none
are returned.
This should probably be replaced by a function in the graph package that identifies leaves, there is nothing special about GO here.
A vector of the node labels for those nodes with no in-edges.
