[R] How to plot the dendrogram or tree for kmeans ?
Why do you think there is one? kmeans is an agglomerative clustering algorithm, not a recursively dividing one. Since there is no clustering hierarchy, so there is no dendrogram. -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Ng Stanley Sent: Thursday, 20 March 2008 12:30 PM To: r-help Subject: [R] How to plot the dendrogram or tree for kmeans ?
