\begin{Description}\relax
xenopuslaevisSYMBOL is an R environment that provides mappings between
manufacturer identifiers and gene abbreviations.
\end{Description}
\begin{Details}\relax
Each manufacturer identifier is mapped to an abbreviation for the
corresponding gene. An \code{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:\bsl{}url{ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Wed Aug 29 14:44:20 2007

Package built Wed Aug 29 14:47:40 2007

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