Annotation of probe identifiers by UniGene identifiers

Description

hgu95av2UNIGENE mappes probe identifiers to UniGene cluster identifiers

Details

This an environment object with key and value pairs. Keys are probe ids and values are the corresponding UniGene cluster ids. Values may be vectors of length 1 or greater depending on whether a given probe id can be mapped to only one or more UniGene cluster ids. NA is assigned to probe ids that can not be mapped to any UniGene cluster id at this time.

Mappings were based on data provided by:

Examples

    # Convert the environment to a list
    xx <- as.list(hgu95av2UNIGENE)
    # 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]]
    }
