Czekanowski's diagram aims to visualize relationships between objects in a simple manner in a two-dimensional matrix. Clusters can be visible in such a diagram. However, the boundaries between these clusters are often very vague and this uncertainty has to be taken into account. The work here presents further development of the RMaCzek package, which now allows for presenting fuzzy clusters in Czekanowski's diagrams-i.e., clustering with uncertain regions.

PL

Diagram Czekanowskiego ma na celu zaprezentowanie podobieństw wewnątrz próbki statystycznej za pomocą dwuwymiarowej macierzy. W diagramie mogą być widoczne skupienia. Jednakże granice między tymi skupieniami mogą być nieostre i niepewność w nich powinna być także przedstawiona. W niniejszej pracy przedstawiamy rozszerzenie pakietu RMaCzek o rozmytą analizę skupień w diagramach Czekanowskiego.
