DEPRECATED Identify the leaves in a GO Graph

Description

This function is DEPRECATED. Use the leaves function in the graph package instead. See the example below.

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.

Usage

GOLeaves(inG)

Arguments

inG An instance of a GO graph.

Details

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.

Value

A vector of the node labels for those nodes with no in-edges.
