\title{Aggregation object.}
\description{
An aggregation method reduces the performance values of the test
(and possibly the training sets) to a single value.
To see all possible implemented aggregations look at \link{aggregations}.

The aggregation can access all relevant information of the result after resampling
and combine them into a single value. Though usually something very simple
like taking the mean of the test set performances is done.

Object members:
\describe{
\item{id (\code{character(1)})}{Name of the aggregation method.}
\item{name (\code{character(1)})}{Long name of the aggregation method.}
\item{properties (\link{character})}{Properties of the aggregation.}
\item{fun (`function(task, perf.test, perf.train, measure, group, pred)])}{Aggregation function.}
}
