runDESeq: Run DESeq for differential expression analysis
In SeqGSEA: Gene Set Enrichment Analysis (GSEA) of RNA-Seq Data: integrating differential expression and splicing

Description Usage Arguments Value Author(s) References See Also Examples

This function provides a wrapper to run DESeq for differential expression analysis. It includes two steps, DESeq::estimateSizeFactors and DESeq::estimateDispersions.

1	runDESeq(geneCounts, label)

`geneCounts`	a matrix containing read counts for each gene, can be the output of `getGeneCount`.
`label`	the sample classification labels.

A CountDataSet object with size factors and dispersion parameters been estimated.
