Usage

build.consistent.graph(g = g, root = "00")

Arguments

g

an object of class graphNEL.

root

name of the class that is on the top-level of the hierarchy (def. root="00").

Details

All nodes not accessible from root (if any) are removed from the graph and printed on stdout.

Value

A graph (as an object of class graphNEL) in which all nodes are accessible from root.

Examples

data(graph);
root <- root.node(g);
G <- graph::addNode(c("X","Y","Z"), g);
G <- graph::addEdge(c("X","Y","Z"), c("HP:0011844","HP:0009810","HP:0012385"), G);
G <- build.consistent.graph(G, root=root);
