Web18 gen 2024 · I have identified Jenks natural breaks in my dataset and aim to leverage them to create discreet ranges based on these Jenks. (See below). I aim to use these natural breaks to create a new column of categorical (dummy variable) data defined based on these Jenk breaks. I am struggling to interpret what the boundaries of those ranges are. WebImplementing the Jenks' natural breaks method, it allows to find the best arrangement of values into different classes. Usage plotJenks (data, n = 3, brks.cex = 0.7, top.margin = 10, dist = 5) Arguments data Vector storing the data. n Number of classes in which the dataset must be broken down (3 by default). brks.cex

The NaturalBreaks coclass uses a statistical formula to determine natural clusters of attribute values. The formula is known as Jenk s method. This attempts to minimize the variance within a class and to maximize the variance between classes. The natural-breaks classification is well suited to uneven distributions of attributes.
