I have this exemple of clustering data
library(cluster)
library(fpc)
input = data.frame(Lon = c(43,43.2,43.5,43.8,44), Lat = c(-12,-11.5,-13,-14,-10.5), Var = c(5,4,7,8,8))
clus <- kmeans(input, centers = 3)
plotcluster(input, clus$cluster)
r <- clusplot(input, clus$cluster, color = T, shade = T, labels = 2, lines = 0)
I want to draw red lines who partition points like show the exemple below.
