Looks for broader regions of enrichment associated with the determined peak positions, adds them to the $npl data as $rs, $re columns.
add.broad.peak.regions(chip.tags,input.tags,bp,window.size=500,z.thr=2)
signal chromosome tag coordinate vectors (e.g. output
of select.informative.tags
optionall control (input) tags
output of find.binding.positions call
window size to be used in calculating enrichment
Z-score corresponding to the Poisson ratio threshold used to flag significantly enriched windows
A structure identical to bp (binding.postions) with two additional columns added (rs and re) corresponding to start and end of the associated significantly enriched region. If no region was associated with a particular peak, NAs values are reported.
