getGeneId: getGene
In shiauck/cummeRbund_on_RSQLite2.0: Analysis, exploration, manipulation, and visualization of Cufflinks high-throughput sequencing data.

Description Usage Arguments Details Value Note Author(s) References Examples

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

1 2	## S4 method for signature 'CuffSet' getGeneId(object, idList)

`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.

None.

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

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

Loyal A. Goff

None.
