## Map between Manufacturer Identifiers and UniGene cluster identifiers

### Description

hgug4100aUNIGENE is an R environment that provides mappings between manufacturer ids and UniGene ids.

### Details

Each manufacturer id is mapped to a UniGene id. An `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:

### Examples

        # Convert the environment to a list
        xx <- as.list(hgug4100aUNIGENE)
        # 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]]
        }
