\item{lynx}{Is a time series with numbers of annual numbers of lynx trapping in
Canada from 1821-1934. Taken from Brockwell & Davis (1991),
this appears to be the series considered by
Campbell & Walker(1977)}
\code{lymphoma} is an \code{\link[Biobase:class.ExpressionSet]{exprSet}}
containing the data of 8 chips
from the lymphoma dataset by Alizadeh et al. (see references). Each
chip represents two samples: on color channel 1 (CH1, Cy3, green) the
common reference sample, and on color channel 2 (CH2, Cy5, red) the
various disease samples. See \code{pData(lymphoma)}. The 9216x16
matrix \code{exprs(lymphoma)} contains the background-subtracted spot
intensities (CH1I-CH1B and CH2I-CH2B, respectively). 
The chip intensity files were downloaded from the Stanford
microarray database. Starting from the link below, this was done by
following the links \emph{Published Data} -> 
\emph{Alizadeh AA, et al. (2000) Nature 403(6769):503-11} -> 
\emph{Data in SMD} -> \emph{Display Data}, and selecting the following 
8 slides:
Then, the script \code{makedata.R} from the \code{scripts} subdirectory
of this package was run to generate the \R data object.
