Anotation of probe identifiers by LocusLink identifiers

Description

hgu95av2LOCUSID mappes probe ids to LocusLink ids corresponding to genes represented by the probe ids.

Details

This an environment object with key and value pairs. Keya are probe ids and values are the corresponding are LocusLink ids. Values are vectors of length 1. NA is assigned to probe ids that can not be mapped to a LocusLink id at this time.

Mappings were based on data provided by:

Examples

    # Convert the environment to a list
    xx <- as.list(hgu95av2LOCUSID)
    # Remove probe ids that do not map to any LOCUSID
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The LOCUSIDs for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
