Map between probeset IDs and gene descriptions

Description

gahgu95bDESCRIPTIONS is an R object that maps probeset identifiers to the corresponding gene name.

Details

Each probeset identifier maps to a named vector containing the gene descriptions. The vector name corresponds to the source of each descrioption. If the gene name is unknown, the vector will contain an NA.

Mappings were based on data provided by: Genecards ( http://www.genecards.org ) on 2009-mag06

Examples

        x <- gahgu95bDESCRIPTIONS
        # Get the probe identifiers that are mapped to a gene description
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the DESCRIPTIONS for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
