circlize (version 0.4.1)

generateRandomBed: Generate random genomic data

Description

Generate random genomic data

Usage

generateRandomBed(nr = 10000, nc = 1, fun = function(k) rnorm(k, 0, 0.5),
    species = NULL)

Arguments

nr

Number of rows

nc

Number of numeric columns / value columns

fun

Function for generating random values

species

species, pass to read.cytoband

Details

The function will uniformly sample positions from the genome. Chromosome names start with "chr" and positions are sorted. The final number of rows may not be exactly as same as nr.

# NOT RUN {
bed = generateRandomBed()
bed = generateRandomBed(nr = 200, nc = 4)
bed = generateRandomBed(fun = function(k) runif(k))
