\title{MicroRNA IDs to Clusters}

\description{
  mirbaseCLUSTER is an R object that provides mappings between
  microRNA identifiers and other microRNA identifiers within a 10kb
  window ('genomic cluster').
}

\details{
  Each microRNA identifier maps to a vector of a microRNA identifiers
  belonging to a cluster (if any beyound itself).
  This information was computed ad-hoc as it is not included in the
  original data tables provided by mirbase.org.
