\begin{Details}\relax
This groups of functions summarize the columns of a given
matrices.

\Itemize{
\item[\code{colSummarizeAvg}] Take means in column-wise manner
\item[\code{colSummarizeAvgLog}] \code{log2} transform the data and
then take means in column-wise manner
\item[\code{colSummarizeBiweight}] Summarize each column using a one
step Tukey Biweight procedure
\item[\code{colSummarizeBiweightLog}] \code{log2} transform the data
and then summarize each column using a one step Tuke Biweight
procedure
\item[\code{colSummarizeLogAvg}] Compute the mean of each column and
then \code{log2} transform it
\item[\code{colSummarizeLogMedian}] Compute the median of each
column and then \code{log2} transform it
\item[\code{colSummarizeMedian}] Compute the median of each column
\item[\code{colSummarizeMedianLog}] \code{log2} transform the data
and then summarize each column using the median
\item[\code{colSummarizeMedianpolish}] Use the median polish to
summarize each column, by also using a row effect (not returned)
\item[\code{colSummarizeMedianpolishLog}] \code{log2} transform the
data and then use the median polish to summarize each column, by
also using a row effect (not returned)
}
