\title{Map between Common Gene Symbol Identifiers and Manufacturer Identifiers}
\description{
  u133x3pALIAS is an R object that provides mappings between
  common gene symbol identifiers and manufacturer identifiers.
}
\details{
  Each gene symbol is mapped to a named vector of manufacturer identifiers. The name
  represents the gene symbol and the vector contains all manufacturer identifiers
  that are found for that symbol. An \code{NA} is reported for any gene symbol that 
  cannot be mapped to any manufacturer identifiers.

  This mapping includes ALL gene symbols including those which are already listed 
  in the SYMBOL map.  The SYMBOL map is meant to only list official gene symbols, 
  while the ALIAS maps are meant to store all used symbols.

  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: 2014-Sep19
