Object returned by the function \code{\LinkA{tune}{tune}}
\end{Description}
\begin{Section}{Slots}
\describe{
\item[\code{hypergrid}:] A \code{data.frame} representing the
grid of values that were tried and
evaluated. The number of columns equals
the number of tuned hyperparameters
and the number rows equals the number
of all possible combinations of the
discrete grids.
\item[\code{tuneres}:] A list whose lengths equals the number
of different \code{learningsets} for which
tuning has been performed and whose
elements are numeric vectors with length
equal to the number of rows of \code{hypergrid} (s.above),
containing the misclassifcation
rate belonging to the respective
hyperparameter/hyperparameter combination.
In order to to get an overview
about the best hyperparmeter/hyperparameter
combination, use the convenience method
\code{\LinkA{best}{best}}
\item[\code{method}:] Name of the classifier that has been tuned.
\item[\code{fold}:] Number of cross-validation fold used for
tuning, s. argument of the same name in
\code{\LinkA{tune}{tune}}
}
\end{Section}
\begin{Section}{Methods}
\describe{
\item[show] Use \code{show(tuninresult-object)} for brief information.
\item[best] Use \code{best(tuningresult-object)} to see which
hyperparameter/hyperparameter combination has performed
best in terms of the misclassification rate,
s. \code{\LinkA{best,tuningresult-method}{best,tuningresult.Rdash.method}}
\item[plot] Use \code{plot(tuningresult-object, iter, which)}
to display the performance of hyperparameter/hyperparameter
combinations graphically, either as one-dimensional or
as two-dimensional (contour) plot,
s. \code{\LinkA{plot,tuningresult-method}{plot,tuningresult.Rdash.method}}
