\begin{Description}\relax
'Makesense' takes either an exprSet object or a matrix of gene
expressions and will produce a smoothed positive and negative strands
for all chromosomes.
\end{Description}
\begin{Usage}
\begin{verbatim}
Makesense(expr, lib, ...)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{expr}] One of an \code{exprSet}, an \code{eSet} or a \code{matrix} of 
gene expressions with genes as rows and columns as samples.
\item[\code{lib}] The name of the Bioconductor annotation data package that
will be used to provide mappings from probes to chromosomal
locations, such as \code{hgu95av2} or \code{hgu133a}.  If
\code{expr} is an \code{exprSet}, the argument defaults to the
\code{annotation} slot of the \code{exprSet}.
\item[\code{...}] Currently, the only optional argument is \code{f}, the
smoother span to be passed to 'lowess'. Its value should
be in the interval of (0,1). This gives the proportion of points in
the plot which influence the smooth at each value. Larger values
give more smoothness.  The default value for this argument is 1/10.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
The \code{expr} argument can either be of class \code{exprSet} or
\code{matrix}, where the latter represents the matrix of gene
expressions.

If the \code{expr} argument is an \code{exprSet}, the \code{lib}
argument will use the \code{annotation} slot.  Users can override this
behaviour and supply their own \code{lib} argument if they wish.  If
the \code{exprSet} has no value associated with the \code{annotation}
slot (which should not happen, but is possible) then the user must
supply the \code{lib} argument manually or the function will throw an
error.
\end{Details}
\begin{Value}
A list of 2 components:
\begin{ldescription}
\item[\code{ans2}] a list, whose components correspond to samples 
in the same order as appearing in the columns of 
'expr'. Each component is also a list, named by chromosomes 
"1"-"22", "X" and "Y". Each named component is again a list 
with two elements named "posS" and "negS", corresponding to the
positive and negative strands of a chromosome, each of which is an object returned by 'lowess'.
\item[\code{lib}] A string giving the name of the annotation data package to
use.  Optional if \code{expr} is an \code{exprSet}.
