slice-methods: Slice an XInteger or XDouble object

In XVector: Foundation of external vector representation and manipulation in Bioconductor

Description

The slice methods for XInteger and XDouble objects create views corresponding to the indices where the data are within the specified bounds. The views are returned in a XIntegerViews or XDoubleViews object.

Usage

## S4 method for signature 'integer'
slice(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)

## S4 method for signature 'XInteger'
slice(x, lower=-.Machine$integer.max, upper=.Machine$integer.max)

## S4 method for signature 'numeric'
slice(x, lower=-Inf, upper=Inf,
      includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)

## S4 method for signature 'XDouble'
slice(x, lower=-.Machine$double.xmax, upper=.Machine$double.xmax,
      includeLower=TRUE, includeUpper=TRUE, rangesOnly=FALSE)

Arguments

x	An XInteger or XDouble object. Alternatively, it can also be an integer or numeric vector.
lower, upper	The lower and upper bounds for the slice.
includeLower, includeUpper	Logical indicating whether or not the specified boundary is open or closed.
rangesOnly	A logical indicating whether or not to drop the original data from the output.

Value

An XIntegerViews or XDoubleViews object if rangesOnly=FALSE.

An IRanges object if rangesOnly=TRUE.

Examples

vec <- as.integer(c(19, 5, 0, 8, 5))
slice(vec, lower=5, upper=8)

set.seed(0)
vec <- sample(24)
slice(vec, lower=4, upper=16)
