WebJan 1, 2013 · One popular method for data segmentation employs the Fisher-Jenks optimal classification algorithm to break data into statistically derived classes such that the variation between classes is maximized and the variation within classes is minimized. This is a non-spatial data partitioning algorithm applied to spatial data. 3.1 Fisher-Jenks Algorithm WebR 划分为类:jenks vs kmeans,r,intervals,R,Intervals,我想把一个向量(长度约为10^5)分成五类。使用packageclassInt中的函数classIntervals时,我想使用style=“jenks”自然中断,但即使对于一个只有500个的小得多的向量,这也需要过多的时间。
