QuantileWidthFunctions: Get quantile positions

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

Description

Function that calculates position of quantiles for CTSS clusters based on distribution of tpm within the cluster

Usage

.get.quant.pos(cumsums, clusters, q)

Arguments

cumsums	Named list of vectors containing cumulative sum for each cluster (returned by 'get.cumsum' function).
clusters	GRanges 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

## Not run:  #because it runs through quantilePositions() anyway.
cumsums  <- CTSScumulativesTagClusters(object, 1)
clusters <- tagClustersGR(object, 1)
.get.quant.pos(cumsums, clusters, c(.1, .9))

## End(Not run)
