## Map between Manufacturer Identifiers and Gene Symbols

### Description

mgu74bSYMBOL is an R environment that provides mappings between manufacturer ids and gene abbreviations.

### Details

Each manufacturer id is mapped to an abbreviation for the corresponding gene. An `NA` is reported if there is no known abbreviation for a given gene.

Symbols typically consist of 3 letters that define either a single gene (ABC) or multiple genes (ABC1, ABC2, ABC3). Gene symbols can be used as key words to query public databases such as Entrez Gene.

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 15:25:25 2005

### Examples

        # Convert the environment to a list
        xx <- as.list(mgu74bSYMBOL)
        if(length(xx) > 0){
            # The symbols for the first two elements of XX
            xx[1:2]
            # Get the first one
            xx[[1]]
        }
