geneList {topGO} | R Documentation

## A toy example of a list of gene identifiers and the respective p-values

### Description

The `geneList` data is compiled from a differential expression analysis of the `ALL` dataset. It contains just a small number of genes with the corespondent p-values. The information on where to find the GO annotations is stored in the `ALL` object.

The `topDiffGenes` function included in this dataset will select the differentially expressed genes, at 0.01 significance level, from `geneList`.

### Usage

    data(geneList)

### Source

Generated using the `ALL` gene expression data. See the "scripts" directory.

### Examples

    data(geneList)

    ## print the object
    head(geneList)
    length(geneList)

    ## the number of genes with a p-value less than 0.01
    sum(topDiffGenes(geneList))
