Helper function to sample random intervals of length interval_width from chromosomes

Description

This function samples a random locus given the chromosome lenght (chr_size) and interval_width from a chromosome

Usage

sample_chromosome_intervals(
  chr_size,
  interval_width,
  strand,
  size,
  replace = TRUE,
  prob = NULL
)

Arguments

chr_size	an integer value defining the length of the chromosome.
interval_width	the length of the interval that shall be sampled.
strand	from which strand should the interval be sampled? Options are: strand = "plus" strand = "minus"
size	a non-negative integer giving the number of sequences that shall be sampled from random genomic loci.
replace	logical value indicating whether sampling should be with replacement. Default: replace = TRUE.
prob	a vector of probability weights for obtaining the elements of the vector being sampled. Default is prob = NULL.
