## Extract top differentially spliced genes

### Description

This function to extract top n differentially spliced genes, ranked by p-values or NBstats.

### Usage

    topDSGenes(RCS, n = 20, sortBy = c("pvalue", "NBstat"))

### Arguments

`RCS` | a ReadCountSet object after running `DSpermutePval`.
`n` | the number of top genes.
`sortBy` | indicating whether p-value or NBstat to be used for ranking genes.

### Value

A table for top n genes. Columns include: geneID, NBstat, pvalue, and padjust.
