In EricSDavis/hictoolsr: An R Package for Hi-C Data Analysis

Define helper function for binning an anchor

Description

Define helper function for binning an anchor

Usage

binAnchor(a, p, res)

Arguments

a	GRanges object
p	Position within anchors to resize the bin. Can be a character or integer vector of length 1 or length(a) designating the position for each element in bedpe. Character options are "start", "end" and "center". Integers are referenced from the start position for '+' and '*' strands and from the end position for the '-' strand.
res	Integer - resolution in which to bin the anchor.

Value

GRanges object that has been shifted and binned into res by p.

Examples

library(GenomicRanges)

## Create example GRanges
gr1 <- GRanges(seqnames = "chr1",
               ranges = IRanges(start = rep(5000,3), end = rep(6000,3)),
               strand = c('+', '-', '*'))

gr2 <- gr1 |> promoters(upstream = 2000, downstream = 200)

## Binning the results
binAnchor(gr1, 'start', 1000)
binAnchor(gr1, 'end', 1000)
binAnchor(gr1, 'center', 1000)

## Bin after shifting back to TSS
binAnchor(gr2, 2000, 1000)
