org.Hs.egGENENAME is an R object that maps entrez gene identifiers to the corresponding gene name.
Each entrez gene identifier maps to a named vector containing the gene
name. The vector name corresponds to the entrez gene identifier. If the
gene name is unknown, the vector will contain an NA.
Gene names currently include both the official (validated by a nomenclature committee) and preferred names (interim selected for display) for genes. Efforts are being made to differentiate the two by adding a name to the vector.
Mappings were based on data provided by: Entrez Gene ftp://ftp.ncbi.nlm.nih.gov/gene/DATA With a date stamp from the source of: 2017-Nov6
AnnotationDb-class for use of
the select() interface.
## select() interface:
## Objects in this package can be accessed using the select() interface
## from the AnnotationDbi package. See ?select for details.
## Bimap interface:
x <- org.Hs.egGENENAME
# Get the gene names that are mapped to an entrez gene identifier
mapped_genes <- mappedkeys(x)
# Convert to a list
xx <- as.list(x[mapped_genes])
if(length(xx) > 0) {
# Get the GENE NAME for the first five genes
xx[1:5]
# Get the first one
xx[[1]]
