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

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

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 Fri Aug 24 00:35:59 2007

Package built: Fri Aug 24 00:42:00 2007

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