If the chromosomal location is unknown, the vector will contain an \code{NA}. Mappings were based on data provided by: Genecards ( http://www.genecards.org ) on 2009-set28 } \examples{ x <- gahgu95av2CHR # Get the probe identifiers that are mapped to a chromosome mapped_probes <- mappedkeys(x) # Convert to a list xx <- as.list(x[mapped_probes]) if(length(xx) > 0) { # Get the CHR for the first five probes xx[1:5] # Get the first one xx[[1]] } } \keyword{datasets}
