\title{Map between Manufacturer Identifiers and UniGene cluster identifiers}
\description{
   hgug4110bUNIGENE is an R environment that provides mappings between
   manufacturer ids and UniGene ids.
}
\details{
  Each manufacturer id is mapped to a UniGene id. An \code{NA} is
  reported if the manufacturer id cannot be mapped to UniGene at this time. 

  A UniGene id represents a cluster of sequences of a gene. Using
  UniGene ids one can query the UniGene database for information about
  the sequences or the LocusLink database for information about the
  genes.  
  
  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

  Package built Tue Oct  4 21:09:30 2005

    # Convert the environment to a list
    xx <- as.list(hgug4110bUNIGENE)
    # Remove probe ids that do no map to any UniGene id
    xx <- xx[!is.null(xx)]
    if(length(xx) > 0){
        # The UniGene ids for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
