Arguments

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, 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.

Examples

if(interactive()){

mart = useMart("ensembl", dataset="hsapiens_gene_ensembl")

#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", mart = mart)
show(g)
