Gene Set Enrichment Analysis is a test thought to find if the position of a group along a list implies some difference. The most know method is the one maintained by the Broad Institute . As it was the first widely used in biology and holds several collection of gene sets. A gene set is a collection of genes related, by either a function or an experiment, it is as fuzzy described as a pathway. In Bioconductor there is the under used tool of BiocViews , a topic for package classificacion. We can find a category for GSEAs under Software>BiologicalQuestion>GeneSetEnrichment . This category list 74 packages at the time of writing, which provide function for Gene Set Enrichment Analysis. It will be too long (and too hard for me) to describe all the packages in that category. However, it doesn't include all the packages that perform gene set enrichment. The first package for GSEA in Bioconductor one should look is GSEABase which provides with tools for reading files from...
