\title{Map between Manufacturer Identifiers and PubMed Identifiers}
\description{
   hgug4110bPMID is an R environment that provides mappings between
   manufacturer ids and PubMed ids.
}
\details{
  Each manufacturer id is mapped to a named vector of PubMed ids. The
  name associated with each vector corresponds to the manufacturer
  id. The length of the vector may be one or greater, depending on how
  many PubMed ids a given manufacturer id is mapped to. An \code{NA} is
  reported for any manufacturer id that cannot be mapped to a PubMed id.

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

  Mappings were based on data provided by:

  Entrez Gene:\url{http://gopher5/compbio/annotationSourceData/ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Tue Oct  4 20:50:58 2005
