## Map between Common Gene Symbol Identifiers and Manufacturer Identifiers

### Description

drosgenome1ALIAS is an R object that provides mappings between common gene symbol identifiers and manufacturer identifiers.

### Details

Each gene symbol is mapped to a named vector of manufacturer identifiers. The name represents the gene symbol and the vector contains all manufacturer identifiers that are found for that symbol. An `NA` is reported for any gene symbol that cannot be mapped to any manufacturer identifiers.

This mapping includes ALL gene symbols including those which are already listed in the SYMBOL map. The SYMBOL map is meant to only list official gene symbols, while the ALIAS maps are meant to store all used symbols.

Mappings were based on data provided by: Entrez Gene ( ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2009-Mar11

### Examples

        # Convert the object to a list
        xx <- as.list(drosgenome1ALIAS2PROBE)
        if(length(xx) > 0){
            # Get the probe identifiers for the first two aliases
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
