Map between Manufacturer Identifiers and Entrez Gene

Description

illuminaMousev2ProbeIDENTREZID is an R object that provides mappings between manufacturer identifiers and Entrez Gene identifiers.

Details

Each manufacturer identifier is mapped to a vector of Entrez Gene identifiers. An NA is assigned to those manufacturer identifiers that can not be mapped to an Entrez Gene identifier at this time.

If a given manufacturer identifier can be mapped to different Entrez Gene identifiers from various sources, we attempt to select the common identifiers. If a concensus cannot be determined, we select the smallest identifier.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2008-Apr2

Examples

        x <- illuminaMousev2ProbeIDENTREZID
        # Get the probe identifiers that are mapped to an ENTREZ Gene ID
        mapped_probes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_probes])
        if(length(xx) > 0) {
          # Get the ENTREZID for the first five probes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
