\title{
pROC Group Generic Functions
}
\description{
Redefine \pkg{base} groupGeneric functions to handle \code{\link{auc}} and \code{\link{ci}} objects properly on operations and mathematical operations.
Attributes are dropped so that the AUC/CI behaves as a numeric value/matrix, respectively.
In the case of AUC, all attributes are dropped, while in CI only the CI-specific attributes are, keeping those necessary for the matrices.
}
\usage{
\special{Math(x, \dots)}
\special{Ops(e1, e2)}
}
\arguments{
\item{x, e1, e2}{\code{\link{auc}} objects, or mixed numerics and \code{auc} objects.
}
\item{\dots}{further arguments passed to other Math methods.
}
}
\seealso{
\code{\link{groupGeneric}}, \code{\link{auc}}
}
\examples{
data(aSAH)
# Create a roc object:
aucobj1 <- auc(roc(aSAH$outcome, aSAH$s100b))
aucobj2 <- auc(roc(aSAH$outcome, aSAH$wfns))
# Math
sqrt(aucobj1)
round(aucobj2, digits=1)
# Ops
aucobj1 * 2
2 * aucobj2
aucobj1 + aucobj2
# With CI
ciaucobj <- ci(aucobj1)
ciaucobj * 2
sqrt(ciaucobj)
