createGODAG {GOFunction}R Documentation

Creation of GO DAG stucture for statistically significant GO terms

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).
