makeRandomPeaks: Make a set of randomly positioned peaks within a predefined...

In walter-ca/Basic4CSim: Basic4CSim: Simulation of 4C-seq data

Description

This helper function creates a set of random peaks with a predefined range for height and width in near-cis. If a fragment library is provided, peak centers are located on a fragment position.

Usage

makeRandomPeaks(vpStart, vpRegionDist = 100000, peakNumber = 6, 
rmaxRange = c(1500, 3000), rsdRange = c(500, 1000), fragmentLibrary = "none")

Arguments

vpStart	viewpoint position
vpRegionDist	length of viewpoint region to either side of the viewpoint where peaks can be simulated
peakNumber	number of peaks to simulate
rmaxRange	range of simulated peaks' heights (maximum)
rsdRange	range of simulated peaks' widths (standard deviation)
fragmentLibrary	optional fragment library with valid fragment positions; if one is provided, peak centers are located at a valid fragment position

Value

Data frame with random peak data for use in addPeak when creating similar, but not identical simulated replicate data
