RleViewsList-class

List of RleViews

Description

An extension of ViewsList that holds only RleViews objects. Useful for storing coverage vectors over a set of spaces (e.g. chromosomes), each of which requires a separate RleViews object.

Details

For more information on methods available for RleViewsList objects consult the man pages for ViewsList-class and view-summarization-methods.

Constructor

: RleViewsList(..., rleList, rangesList): Either ... or the rleList/rangesList couplet provide the RleViews for the list. If ... is provided, each of these arguments must be RleViews objects. Alternatively, rleList and rangesList accept Rle and IntegerRanges objects respectively that are meshed together for form the RleViewsList.
: Views(subject, start=NULL, end=NULL, width=NULL, names=NULL): Same as RleViewsList(rleList = subject, rangesList = start).

Coercion

In the code snippet below, from is an RleViewsList object:

: as(from, "IRangesList"): Creates an IRangesList object containing the view locations in from.

Examples

## Rle objects
subject1 <- Rle(c(3L,2L,18L,0L), c(3,2,1,5))
set.seed(0)
subject2 <- Rle(c(0L,5L,2L,0L,3L), c(8,5,2,7,4))

## Views
rleViews1 <- Views(subject1, 3:0, 5:8)
rleViews2 <- Views(subject2, subject2 > 0) 

## RleList and IntegerRangesList objects
rleList <- RleList(subject1, subject2)
rangesList <- IRangesList(IRanges(3:0, 5:8), IRanges(subject2 > 0))

## methods for construction
method1 <- RleViewsList(rleViews1, rleViews2)
method2 <- RleViewsList(rleList = rleList, rangesList = rangesList)
identical(method1, method2)

## calculation over the views
viewSums(method1)
