generate_random_genomic_range: Generate data frames of random genomic ranges

In antonio-mora/vennRanges: Venn Diagrams of Genomic Ranges

Description

This is a function to generate dataframes of genomic ranges in a fast way. It is not meant to work as a background for statistical analyses, but only to allow fast testing of all the other functions. This function can take four arguments: The number of chromosomes to be included in the resulting dataframe, a range to sample the sizes of each genomic range (using R "sample" function), a range to sample the sizes of the inter-range distances (using again "sample"), and the number of ranges we want to create per chromosome.

Usage

generate_random_genomic_range(number_chrom, size_range, size_inter_range, number_ranges_per_chrom)

Arguments

number_chrom	An integer with the number of chromosomes to be created. Default value: 5.
size_range	A vector with the minimum and maximum size of each genomic range. Default value: c(50, 1000).
size_inter_range	A vector with the minimum and maximum size of the distance between each pair of genomic ranges. Default value: c(50, 2000).
number_ranges_per_chrom	An integer with the number of desired genomic ranges per chromosome. Default value: 20.

Value

A dataframe with the specified number of chromosomes and genomic ranges per chromosomes, where genomic ranges and inter-ranges distances are randomly chosen from an uniform distribution between specified integer values.

Examples

a <- generate_random_genomic_ranges()
b <- generate_random_genomic_ranges(19, c(10, 1000), c(10, 5000), 100)
head(a)
head(b)
