clamix-package: Clustering modal valued symbolic data

In clamix: Clustering modal multi valued symbolic data

Description

Two clustering methods for symbolic objects are implemented: the adapted leaders method and the adapted agglomerative hierarchical clustering Ward's method. Additional: classes symObject and symData for saving symbolic objects with print and summary (for symData) methods and functions to help producing such objects are implemented.

Additional functions to help cluster descriptions that are implemented: computeTotal, create.symData, empty.symObject, encodeSO, makeEnc, specContrasts.

Datasets: popul06f, popul06m, a list of data.frames: TIMSSSlo.

Adapted agglomerative and hierarchical clustering methods are compatible - they can be viewed as two approaches for solving the same clustering optimization problem. In the obtained clustering to each cluster is assigned its leader. The descriptions of the leaders offer simple interpretation of the clusters' characteristics. The leaders method enables us to efficiently solve clustering problems with large number of units; while the agglomerative method is applied on the obtained leaders and enables us to decide upon the right number of clusters on the basis of the corresponding dendrogram.
