\title{Map Systematic ORF identifiers with SGD accession numbers}  
\description{ 
  org.Sc.sgdSGD is an R object that contains mappings between 
  Systematic ORF accessions and SGD accession numbers.    
}
\details{
  This object is a simple mapping of Systematic ORF Accession Numbers to
  SGD identifiers.
}

\examples{
    x <- org.Sc.sgdSGD
    # Get the Systematic ORF Accessions that are mapped to a SGD ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the SGD gene IDs for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }
