Changes in version 0.3 (2023-12-06)                   

  - The function now can take as input a dataset in 'long' format;
    therefore, units can now feature a different number of observations;
  - Parameter 'target.var' and 'group.var' added;
  - Parameter 'silh.col' added to provide the option to give by-cluster
    colours to the silhouette plot;
  - In the returned values, 'units.by.cluster' replaces the earlier
    'dataset.w.cluster.assignment';
  - Example of datasets in 'wide' and 'long' format added to the help
    documentation;
  - Fixes and improvements content- and layout-wise to the help
    documentation.
