rgug4130aGENENAME is an R object that maps manufacturer identifiers to the corresponding gene name.
Each manufacturer identifier maps to a named vector containing the gene
name. The vector name corresponds to the manufacturer identifier. If the gene
name is unknown, the vector will contain an NA.
Gene names currently include both the official (validated by a nomenclature committee) and preferred names (interim selected for display) for genes. Efforts are being made to differentiate the two by adding a name to the vector.
Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2007-Aug23
x <- rgug4130aGENENAME
# Get the probe identifiers that are mapped to a gene name
mapped_probes <- mappedkeys(x)
# Convert to a list
xx <- as.list(x[mapped_probes])
if(length(xx) > 0) {
# Get the GENENAME for the first five probes
xx[1:5]
# Get the first one
xx[[1]]
