GRanges universe for a set of conditions and replicates

Usage

gr_universe(
  grlist,
  min_consensus,
  resize_pre = NULL,
  resize_across = NULL,
  resize_post = NULL,
  anchor = "center"
)

grlist: A list where each element is a list of GRanges objects. If the list is named, a source column will be added to the final consensus
min_consensus: Minimum consensus needed to merge peaks from the same condition (replicates)
resize_pre: Resize replicate peaks before calling consensus - Default NULL
resize_across: Resize peaks before merging across conditions. Resizing to a small size here will make sure that proximal peaks will not get merged, but might incur in certain level of overlap if resize_post is larger.
resize_post: Resize final group of peaks to a fixed size. Default NULL
anchor: Where to anchor for resizing. Defaults to center.
