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_id, hgnc_symbol (for hugo gene symbol), ensembl_gene_id, unigene, agilentprobe, affy_hg_u133_plus_2, refseq_dna, etc.

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_id", mart = mart)
show(g)
