Pairwise Semantic Similarity for a List of Genes

Description

Given a list of genes, this function calculates pairwise semantic similarities.

Usage

mgeneSim(genes, ont = "MF",  organism="human", measure="Wang", drop= "IEA")

Arguments

genes A list of entrez gene IDs.
ont One of "MF", "BP", and "CC" subontologies.
measure One of "Resnik", "Lin", "Rel", "Jiang" and "Wang" methods.
organism One of "human", "rat", "mouse", "fly" and "yeast".
drop A set of evidence codes based on which certain annotations are dropped. Use NULL to keep all GO annotations.

Value

simMatrix A Matrix of Pairwise Semantic Similarities
