\title{Map between PubMed Identifiers and Manufacturer Identifiers}
\description{
  mgu74aPMID2PROBE is an R object that provides mappings between
  PubMed identifiers and manufacturer identifiers.
}
\details{
  Each PubMed identifier is mapped to a named vector of manufacturer identifiers. The
  name represents the PubMed identifier and the vector contains all manufacturer
  identifiers that are represented by that PubMed identifier. The length of the vector
  may be one or longer, depending on how many manufacturer identifiers are
  mapped to a given PubMed identifier.

  Titles, abstracts, and possibly full texts of articles can be obtained
  from PubMed by providing a valid PubMed identifier. The pubmed function of
  annotate can also be used for the same purpose
  
  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: 2010-Mar1
