hu6800CHR mappes probe ids to chromosome numbers where the genes corresponding to the probe ids reside
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
