## A package to perform run Gene Set Enrichment across genomic platforms

### Description

Gene sets analysis considers whether genes sharing a biological property also behave in a related way in experimental data. This technique is commonly used in high throughput genomic analyses to assist results interpretation, and has been successfully applied in cancer genome projects for integrating information from multiple genome-wide assays. The `RTopper` package uses gene sets analysis to overcome the diversity of genomic data providing the statistical framework for integration across data types.

### RTopper package features

`Rtopper` enables two gene set-based data integration approaches:

1

  Integration+GSA: computing integrated gene-to-phenotype association scores, followed by conventional gene sets analysis;

2

  GSA+Integration: computing consensus significance score after all data types are analyzed individually;

3

  Use of alternative enrichment test: `RTopper` uses the Wilcoxon rank-sum test for enrichment testing, however alternative tests can be defined and used;

4

  Multiple testing correction: `RTopper` enables adjustment of p-values obtained from enrichment analysis;
