| mgu74cv2GENENAME {mgu74cv2} | R Documentation |
mgu74cv2GENENAME is an R environment that maps manufacturer identifiers to the corresponding gene name.
Each manufacturer id maps to a named vector containing the gene
name. The vector name corresponds to the manufacturer id. 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:http://gopher5/compbio/annotationSourceData/ftp.ncbi.nlm.nih.gov/gene/DATA/. Built: Source data downloaded from Entrez Gene on Tue May 17 15:58:38 2005

# Convert to a list
xx <- as.list(mgu74cv2GENENAME)
# Remove probes that do not map to any GENENAME
xx <- xx[!is.na(xx)]
if(length(xx) > 0){
# Gets the gene names for the first five probe ids
xx[1:5]
# Get the first one
xx[[1]]
