Mappings between probe identifiers and the chromosome numbers the genes represented by the probe ids reside


Each chromosome of a given organism is assigned a number or letter for labeling purpose. hu6800CHR maps probe ids to the numbers or letters labeling chromosomes where the genes corresponding to the probe ids reside


Since a given gene may be found in more than one chromosomes, each probe id is mapped to a character vector of length 1 or greater. Probe ids that can not be mapped to any chromosome at the time when the package was built are assinged NAs.

Mappings were based on data provided by:

        # Remove probe ids that do not map to any CHRLOC
        xx <- xx[!]
        if(length(xx) > 0){
            # Get the chromosome number for the first five probes
            # Get the first one
