## Map between Manufacturer Identifiers and Entrez Gene

### Description

hu35ksubbENTREZID 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 2007-Aug23

### Examples

            x <- hu35ksubbENTREZID
            # 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]]
            }
