QuantileWidthFunctions: Get quantile positions

In charles-plessy/CAGEr: Analysis of CAGE (Cap Analysis of Gene Expression) sequencing data for precise mapping of transcription start sites and promoterome mining

Get quantile positions

Description

Private function that calculates position of quantiles for CTSS clusters based on distribution of tags within the clusters.

Usage

.get.quant.pos(cum.sums, clusters, q)

Arguments

cum.sums	Named list of vectors containing cumulative sum for each cluster (returned by the CTSScumulativesTagClusters or CTSScumulativesCC function).
clusters	TagClusters or ConsensusClusters object representing tag clusters or consensus clusters.
q	desired quantiles - single value or a vector of values.

Value

Returns the clusters object with one more metadata column per value in q, containing Rle integers giving the relative distance of the quantile boundaries to the start position.

Examples

cum.sums  <- RleList(`1` = Rle(1), `2` = cumsum(Rle(c(1, 1, 1, 2, 4, 0, 1, 1))))
clusters <- GRanges(c("chr1:100-101", "chr1:120-127"))
CAGEr:::.get.quant.pos(cum.sums, clusters, c(.2, .8))
