sampleRanges: sampleRanges

Description

Sample ranges with same widths of input rannges from a set of subject ranges.

Usage

sampleRanges(inputGRanges, subjectGRanges, ignore.strand=TRUE)

Arguments

inputGRanges

The input GRanges.

subjectGRanges

The subject GRanges.

ignore.strand

When set to TRUE, the strand information is ignoreed during the sampling. Otherwise, the input ranges on positvie strand will only sample from subject ranges on positvie strand.

Value

A GRanges object with the same length and widths of inputGRanges.

Examples

  library(GenomicRanges)
  inputGRanges <- GRanges(seqnames=c("chr1", "chr2"), 
                         range=IRanges(start=c(2L, 10L), end=c(6L, 15L)),
                          strand=c("+", "-"))

  subjectGRanges <- GRanges(
                            seqnames=c("chr1", "chr1", "chr1", "chr1", 
                                       "chr2", "chr2"),
                            ranges=IRanges(start=c(20L, 20L, 30L, 30L, 7L, 25L),
                                           end=c(50L, 50L, 32L, 32L,9L, 55L)),
                            strand=c("+","-", "+", "-", "+","-"))
