\title{Mappings between PubMed identifiers and probe identifiers}
\description{
  PubMed \url{http://www.ncbi.nlm.nih.gov/PubMed/} includes over 14
  million citations for biomedical articles back to the 1950's. Each
  article has a unique PubMed identifier. hgu2beta7PMID2PROBE maps
  PubMed identifiers to probe identifiers representing genes cited by
  the publications identified by the PubMed identifiers  
}
\details{
  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:

        xx[1:2]
        # Get the first one
