This function takes a spotoroo object to produce a summary of the
clustering results. It can be called by summary.spotoroo().
Arguments
- result
spotorooobject. A result of a call tohotspot_cluster().- cluster
Character/Integer. If "all", summarize all clusters. If an integer vector is given, summarize corresponding clusters.
Examples
