问题描述

我正在尝试为k均值聚类绘制轮廓图，但是这些条几乎是不可见的.如何使该图表清晰可见?

I am trying to make a silhouette plot for a k-means clustering, but the bars are almost invisble. How can I make this chart legible?

示例代码:

require(cluster)

X <- EuStockMarkets
kmm <- kmeans(X, 8)

D <- daisy(X)
plot(silhouette(kmm$cluster, D), col=1:8)

示例输出:

推荐答案

要解决此问题，请将边框设置为NA:

To fix this, set the border to NA:

plot(silhouette(kmm$cluster, D), col=1:8, border=NA)
