Matrixvisualisaties per groep

Regels extraheren met apriori

rules = apriori(data_trx, 
                parameter = list(
                  supp = 1/7,
                  conf = 0.6,
                  minlen = 2)
)

Methode grouped

plot(rules, method = "grouped")

gegroepeerd

Matrixvisualisaties per groep

Gegroepeerde matrix met andere metriek

plot(rules, 
     method = "grouped",
     measure = "lift",
     shading = "confidence")

gegroepeerd2

Parallelcoördinatenplots

Regels genereren en de plot aanroepen

plot(rules, method = "paracoord")
