Dear Bioconductor connoisseurs, Is there an algorithm to produce a random set of genomic positions?
In more detail now: I have two sets of ChIP-seq peak locations. Say they are 10000 peaks each. There is partial overlap between both sets. The question that I need to answer is whether or not that overlap is statistically significant. I can answer that question if I can randomly shuffle one of the sets many times and compute the overlap with the non-shuffled set. IMPORTANT: some portions of the mouse genome must be excluded because their are repetitive or poorly sequenced. For instance, those familiar with the mm9 assembly know that the first 3 million bases of almost all chromosomes are to be excluded.
