\begin{Description}\relax
The expression levels of approximately 
4600 cellular RNA transcripts were assessed in CD4+ T cell lines at different 
times after infection with HIV-1BRU using DNA microarrays.
There are two data sets, which are part of a dye-swap experiment with
replicates,
representing the Cy3 (green) absorption intensities for channel 1
(\code{hiv1raw})
and the Cy5 (red) absorption intensities for channel 2
(\code{hiv2raw}).
\end{Description}
\begin{Usage}
\begin{verbatim}data(hiv1raw)\end{verbatim}
\end{Usage}
\begin{Format}\relax
This data represents a block within a 
microarray image with 12x32 spots.
It is stored as a vector of length 450,000 representing
a 450x1000 matrix (ordered by column) of intensities encoded
for compact (16-bit TIFF) storage.
\end{Format}
\begin{Details}\relax
The intensities can be obtained from this data by first 
subtracting them from 65535, then squaring, then multiplying by 
a scale factor 4.71542407E-05.
In other words, a number \code{x} in the \code{hiv1} data set corresponds
to intensity  \begin{alltt}(256*256 - 1 - x)\textasciicircum{}2*.0000471542407\end{alltt}. \bsl{}
