\title{Map between Entrez Gene IDs and Genes}
\description{
  org.Hs.egGENENAME is an R object that maps entrez gene
  identifiers to the corresponding gene name.
}

\details{
  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 \code{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

## 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]]
}
