\begin{Description}\relax
A function giving a table of true versus predicted values,
from a nearest shrunken centroid fit.
\end{Description}
\begin{Usage}
\begin{verbatim}
pamr.confusion(fit, threshold, extra=TRUE)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{fit}] The result of a call to pamr.train or pamr.cv
\item[\code{threshold}] The desired threshold value
\item[\code{extra}] Should the  classwise and overall error rates be returned?
Default TRUE
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
\code{pamr.confusion} Gives a cross-tabulation of true versus
predicted classes for the fit returned by pamr.train or pamr.cv,
at the specified threshold.
