Map between TAIR Identifiers and Gene Symbols

Description

org.At.tairSYMBOL is an R object that provides mappings between TAIR identifiers and gene abbreviations.

Details

Each TAIR identifier 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: Tair ftp://ftp.arabidopsis.org/home/tair/Genes/gene\_aliases.20110720.txt With a date stamp from the source of: 2011-May27

Examples

        x <- org.At.tairSYMBOL
        # Get the tair identifiers that are mapped to a gene symbol
        mapped_genes <- mappedkeys(x)
        # Convert to a list
        xx <- as.list(x[mapped_genes])
        if(length(xx) > 0) {
          # Get the SYMBOL for the first five genes
          xx[1:5]
          # Get the first one
          xx[[1]]
        }
