km = kmeans(FourA，3(公里$集群[1]
1 1 1 2 1 1 2 2 2 2 3 2 ...如何使用 km$cluster 向量创建 3 个新数组，以便我可以使用不同的字符/颜色绘制包含三个聚类的图形？
供您参考
x <- rbind(matrix(rnorm(100, sd = 0.3), ncol = 2),
matrix(rnorm(100, mean = 1, sd = 0.3), ncol = 2))
cl <- kmeans(x, 3, nstart = 25)
plot(x, col = cl$cluster)
points(cl$centers, col = 1:3, pch = 8)
