geneSets.sim: Compute the similarities between a collection of gene sets.

In massiveGST: Competitive Gene Sets Test with the Mann-Whitney-Wilcoxon Test

Compute the similarities between a collection of gene sets.

Description

Compute the similarities between a collection of gene sets using a convex function of the Jaccard and overlap indeces.

Usage

geneSets.sim(gs, eps = 0.25)

Arguments

gs	a character vector of gene-sets.
eps	a real value between 0.0 and 1.0 controlling the contribution of the Jaccard and overlap similaties to their convex combination; eps = 0.25 (default), see details.

Details

The similarity between the gene-set is computed a convex combination of the Jaccard and overlap similarities. See the reference for further details.

Value

returns an object of class "dist", where the values are the similaties between gene sets.
