  end
  1. Ensure clope is started before your application:
  def application do
    [applications: [:clope]]
  end

How to use

iex> input = [
  {"transaction1", ["object1", "object2", "object3"]},
  {"transaction2", ["object1", "object5"]},
  {"transaction3", ["object2", "object3"]},
  {"transaction4", ["object1", "object5"]}
]
iex> result = input |> Clope.clusterize(2)
[
  [
    {"transaction1", ["object1", "object2", "object3"]},
    {"transaction3", ["object2", "object3"]}
  ],
  [
    {"transaction2", ["object1", "object5"]},
    {"transaction4", ["object1", "object5"]}
  ]
