\name{SHDZCHR} \alias{SHDZCHR} \title{Map Manufacturer IDs to Chromosomes} \description{ SHDZCHR is an R object that provides mappings between a manufacturer identifier and the chromosome that contains the gene of interest. } \details{ Each manufacturer identifier maps to a vector of chromosomes. Due to inconsistencies that may exist at the time the object was built, the vector may contain more than one chromosome (e.g., the identifier may map to more than one chromosome). If the chromosomal location is unknown, the vector will contain an \code{NA}. Mappings were based on data provided by: Entrez Gene ftp://ftp.ncbi.nlm.nih.gov/gene/DATA With a date stamp from the source of: 2012-Mar7 } \examples{ x <- SHDZCHR # 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}
