\title{Summarize views on an XInteger or XDouble object}
\description{
The \code{viewMins}, \code{viewMaxs}, \code{viewSums}, and \code{viewMeans}
methods described here calculate respectively the minima, maxima, sums,
and means of the views in an \link{XIntegerViews} or \link{XDoubleViews}
object.
}
\usage{
## "viewMins" methods:
## -------------------
\S4method{viewMins}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewMins}{XDoubleViews}(x, na.rm=FALSE)
## "viewMaxs" methods:
## -------------------
\S4method{viewMaxs}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewMaxs}{XDoubleViews}(x, na.rm=FALSE)
## "viewSums" methods:
## -------------------
\S4method{viewSums}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewSums}{XDoubleViews}(x, na.rm=FALSE)
## "viewMeans" methods:
## --------------------
\S4method{viewMeans}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewMeans}{XDoubleViews}(x, na.rm=FALSE)
## "viewWhichMins" methods:
## ------------------------
\S4method{viewWhichMins}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewWhichMins}{XDoubleViews}(x, na.rm=FALSE)
## "viewWhichMaxs" methods:
## ------------------------
\S4method{viewWhichMaxs}{XIntegerViews}(x, na.rm=FALSE)
\S4method{viewWhichMaxs}{XDoubleViews}(x, na.rm=FALSE)
}
\arguments{
\item{x}{
An \link{XIntegerViews} or \link{XDoubleViews} object.
}
\item{na.rm}{
Logical indicating whether or not to include missing values in the results.
}
}
\value{
A numeric vector of the length of \code{x}.
}
\note{
For convenience, methods for \code{min}, \code{max}, \code{sum},
\code{mean}, \code{which.min} and \code{which.max} are provided as
wrappers around the corresponding \code{view*} functions (which might
be deprecated at some point).
