getGene: Retrieves gene annotation information given a vector of...
In biomaRt: Interface to BioMart databases (i.e. Ensembl)

Description Usage Arguments Author(s) Examples

This function retrieves gene annotations from Ensembl given a vector of identifiers. Annotation includes chromsome name, band, start position, end position, gene description and gene symbol. A wide variety of identifiers is available in Ensembl, these can be found with the listFilters function.

1	getGene( id, type, mart)

`id`	vector of gene identifiers one wants to annotate
`type`	type of identifier, possible values can be obtained by the listFilters function. Examples are entrezgene\_id, hgnc\_symbol (for hugo gene symbol), ensembl\_gene\_id, unigene, agilentprobe, affy\_hg\_u133\_plus\_2, refseq\_dna, etc.
`mart`	object of class Mart, containing connections to the BioMart databases. You can create such an object using the function useMart.

#example using affy id

g = getGene( id = "1939_at", type = "affy_hg_u95av2", mart = mart)
show(g)

#example using Entrez Gene id

g = getGene( id = "100", type = "entrezgene_id", mart = mart)
show(g)
