createGODAG: Creation of GO DAG stucture for statistically significant GO...

In GOFunction: GO-function: deriving biologcially relevant functions from statistically significant functions

Description

To plot the relationship between statistically significant GO terms, this function creates a GO DAG structure for these terms.

Arguments

sigNodes	sigNodes is the statistically significant GO terms found by "enrichmentFunction" function.
ontology	The default ontology is "BP" (Biological Process). The "CC" (Cellular Component) and "MF" (Molecular Function) ontologies can also be used.

Value

This function returns a object of 'graphNEL' class.

Note

This function simulates the related program in TopGO (Alexa, A. et al. (2006) Improved scoring of functional groups from gene expression data by decorrelating GO graph structure. Bioinformatics, 22, 1600-1607).
