The dimensional groups can also be set when the constructor is called:

  my $clp = Algoritm::ClusterPoints->new(
                       dimensional_groups => [[0, 1], [2]],
                       ...);

Usually, when using dimensional groups, you would also want to use the
C<scales> method to set different scales for every dimension group.

Following with the previous example, supposing X and Y are given in
meters and T in seconds, to find the clusters with radius between
points of 1Km and 2 days, the following scales should be used:

  my $spc_scl = 1/1000;
  my $tmp_scl = 1/(2 * 24 * 60 * 60);

  $clp = Algorithm::ClusterPoints->new(
                     dimensional_groups => [[0, 1], [2]],
                     scales => [$spc_scl, $spc_scl, $tmp_scl],
                     ...);
