Annotation of probe ids by chromosome numbers the corresponding genes reside

Description

hgu95av2CHR mappes probe ids to chromosome numbers where the genes corresponding to the probe ids reside

Details

This is an environment object with key and value pairs. Keys are probe ids and values are the mapped chromosome numbers are. Values are vectors of length 1 or more depending on whether a probe id can be mapped to only one or more chromosomes. Mappings between probe ids and chromosomes were obtained through their mappings to LocusLink ids.

Mappings were based on data provided: LocusLink built: March 3, 2004. ftp://ftp.ncbi.nih.gov/refseq/LocusLink/LL_tmpl.ga

Package built: Wed Mar 3 16:27:29 2004

Examples

        # Convert to a list
        xx <- as.list(hgu95av2CHR)
        # Remove probe ids that do not map to any CHRLOC
        xx <- xx[!is.na(xx)]
        if(length(xx) > 0){
            # Get the chromosome number for the first five probes
            xx[1:5]
            # Get the first one
            xx[[1]]
        }
