fromSamplesToChrsGRangesList {DEScan2} | R Documentation

## fromSamplesToChrsGRangesList

### Description

converts a GRangesList orgnized per samples to a GRangesList organized per Chromosomes where each element is a GRangesList of samples.

### Usage

    fromSamplesToChrsGRangesList(samplesGRangesList)

### Arguments

`samplesGRangesList` | a GRangesList of samples. Tipically generaed by findPeaks function.

### Value

A GRangesList of chromosomes where each element is a GRanges list of samples.

### Examples

    library("GenomicRanges")
    gr1 <- GRanges(
                seqnames=Rle(c("chr1", "chr2", "chr1", "chr3"), c(1, 3, 2, 4)),
                ranges=IRanges(1:10, end=10),
                strand=Rle(strand(c("-", "+", "*", "+", "-")), c(1, 2, 2, 3, 2)),
                seqlengths=c(chr1=11, chr2=12, chr3=13))
    gr2 <- GRanges(
                seqnames=Rle(c("chr1", "chr4", "chr1", "chr3"), c(1, 3, 2, 4)),
                ranges=IRanges(1:10, end=10),
                strand=Rle(strand(c("-", "+", "*", "+", "-")), c(1, 2, 2, 3, 2)),
                seqlengths=c(chr1=11, chr4=12, chr3=13))
    sgrl <- GRangesList(gr1, gr2)
    names(sgrl) <- c("samp1", "samp2")
    (chrGrlSampGr <- fromSamplesToChrsGRangesList(sgrl))
