gsIntersect

For two character vectors, returns the set of shared elements. This is used by GSNA to find shared genes
in two gene sets.

Create networks of gene sets, infer clusters of functionally-related gene sets based
on similarity statistics, and visualize the results. This package simplifies and accelerates
interpretation of pathways analysis data sets. It is designed to work in tandem with standard
pathways analysis methods, such as the 'GSEA' program (Gene Set Enrichment Analysis), CERNO
(Coincident Extreme Ranks in Numerical Observations, implemented in the 'tmod' package) and others.
Inputs to 'GSNA' are the outputs of pathways analysis methods: a list of gene sets (or "modules"),
pathways or GO-terms with associated p-values. Since pathways analysis methods may be used to
analyze many different types of data including transcriptomic, epigenetic, and high-throughput
screen data sets, the 'GSNA' pipeline is applicable to these data as well. The use of 'GSNA' has
been described in the following papers:
