\title{Slice an XInteger or XDouble object}
\description{
The \code{\link[IRanges]{slice}} methods for \link{XInteger} and
\link{XDouble} objects create views corresponding to the indices where
the data are within the specified bounds. The views are returned in a
\link{XIntegerViews} or \link{XDoubleViews} object.
}
\usage{
\S4method{slice}{integer}(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)
\S4method{slice}{XInteger}(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)
\S4method{slice}{numeric}(x, lower=-Inf, upper=Inf,
includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)
\S4method{slice}{XDouble}(x, lower=-.Machine$double.xmax, upper=.Machine$double.xmax,
includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)
}
\arguments{
\item{x}{
An \link{XInteger} or \link{XDouble} object. Alternatively, it can also
be an integer or numeric vector.
}
\item{lower, upper}{
The lower and upper bounds for the slice.
}
\item{includeLower, includeUpper}{
Logical indicating whether or not the specified boundary is open or closed.
}
\item{rangesOnly}{
A logical indicating whether or not to drop the original data from the
output.
}
}
\value{
An \link{XIntegerViews} or \link{XDoubleViews} object
if \code{rangesOnly=FALSE}.
An \link[IRanges]{IRanges} object if \code{rangesOnly=TRUE}.
