## Mappings between probe identifiers and the PubMed identifiers for the publication where functional annotation of genes corresponding to the probe ids were made

### Description

NCBI 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

### Details

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:

### Examples

        # 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]]
        }
