annaffyMAP {annaffy} | R Documentation |
This is an R environment object containing key and value pairs for the mappings between probe identifiers (key) and cytoband locations (value). Keys can be accessed using ls(name) and values using get(key, name) or multiget(keys, name). Values are vectors of length 1. NA is assigned to probe identifiers that can not be mapped to any cytoband at this time. Mappings are obtained using data from LocusLink (www.ncbi.nlm.nih.gov/LocusLink) based on unified mappings between probe identifiers and LocusLink ids.
