\begin{Description}\relax
hgug4100aLOCUSID is an R environment that provides mappings between
manufacturer ids and Entrez Gene ids.
\end{Description}
\begin{Details}\relax
Each manufacturer id is mapped to a vector of Entrez Gene ids. An
\code{NA} is assigned to those manufacturer ids that can not be mapped
to an Entrez Gene id at this time.

If a given manufacturer id can be mapped to different Entrez Gene ids
from various sources, we attempt to select the common ids. If a
concensus cannot be determined, we select the smallest id.

Mappings were based on data provided by:

Entrez Gene:\url{ftp://ftp.ncbi.nlm.nih.gov/gene/DATA/}. Built: Source data downloaded from Entrez Gene on Sat Mar 25 23:34:25 2006

Package built: Sat Mar 25 23:51:06 2006

\begin{Examples}
\begin{ExampleCode}
    # Convert the environment to a list
    xx <- as.list(hgug4100aLOCUSID)
    # Remove probe ids that do not map to any LOCUSID
    xx <- xx[!is.na(xx)]
    if(length(xx) > 0){
        # The LOCUSIDs for the first two elements of XX
        xx[1:2]
        # Get the first one
        xx[[1]]
    }
