getGeneId {cummeRbund} | R Documentation

## getGene

### Description

A helper function to retrieve the gene_ids for a given list of feature ids (e.g. isoform_ids, tss_group_ids, or CDS_ids). This should not be called directly by the user

### Usage

    ## S4 method for signature 'CuffSet'
    getGeneId(object, idList)

### Arguments

`object` | An object of class 'CuffSet' (Primary 'pointer' object for Cufflinks data).
`idList` | A character string to identify the identifiers for which you would like to retrieve corresponding gene_id values.

### Details

None.

### Value

Returns a vector of gene_id values corresponding to genes from which idList are sub-features.

### Note

Right now, this does not return an error if it cannot find a gene. (this is probably a bad thing...)

### Author(s)

### Examples

    	cuff<-readCufflinks(system.file("extdata", package="cummeRbund")) #Read cufflinks data and create master CuffSet object
    	sampleFeatureIds<-sample(featureNames(isoforms(cuff)),10)
    	correspondingGeneIds<-getGeneId(cuff,sampleFeatureIds) # Retrieve gene_id values for parent genes of sampleFeatureIds.
