\begin{Description}\relax
chickenUNIPROT is an R object that contains mappings between 
Entrez Gene identifiers and Uniprot accession numbers.
\end{Description}
\begin{Details}\relax
This object is a simple mapping of Entrez Gene identifiers
\url{http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene} to Uniprot
Accessions.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Sep2
\end{Details}
\begin{Examples}
\begin{ExampleCode}
    x <- chickenUNIPROT
    # Get the entrez gene IDs that are mapped to an Uniprot ID
    mapped_genes <- mappedkeys(x)
    # Convert to a list
    xx <- as.list(x[mapped_genes])
    if(length(xx) > 0) {
      # Get the Uniprot IDs for the first five genes
      xx[1:5]
      # Get the first one
      xx[[1]]
    }
\end{ExampleCode}
