\title{Map between Manufacturer IDs and Genes}
\description{
  u133x3pGENENAME is an R object that maps manufacturer
  identifiers to the corresponding gene name.
}
\details{
  Each manufacturer identifier maps to a named vector containing the gene
  name. The vector name corresponds to the manufacturer 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
