\begin{Description}\relax
NCBI
\url{http://www.ncbi.nlm.nih.gov/projects/GeneRIF/GeneRIFhelp.html}
allows users to add functional annotation of genes by providing a
PubMed identifier for the publication where the annotation was initially
made and a concise phrase describing the function. hgu2beta7GRIF maps
probe identifiers to the PubMed identifiers for the publication
reporting the functions of genes corresponding to the probe identifiers
\end{Description}
\begin{Details}\relax
Probe ids are only mapped to the PubMed ids. Efforts are being made to
also include the concise phrase describing the function of a gene.  

Mappings were based on data provided by:

\begin{Examples}
\begin{ExampleCode}
    # Convert the environment to a list
    xx <- as.list(hgu2beta7GRIF)
    # Remove probe ids that do not map to any PubMed id
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The unique PubMed ids for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
