We can now display the results of the operation as follows:

    out.println(som.toString()); 

The iris dataset uses five attributes: sepallength, sepalwidth, petallength, petalwidth, and class. The first four attributes are numeric and the fifth has three possible values: Iris-setosa, Iris-versicolor, and Iris-virginica. The first part of the abbreviated output that follows identified four clusters and the number of instances in each cluster. This is followed by statistics for each of the attributes:
