R-系统图标签到载体

R-系统图标签到载体,r,hierarchical-clustering,R,Hierarchical Clustering,如果我们使用apepackage从层次聚类中绘制系统图 phy <- hclust(dist(mtcars)) plot(as.phylo(phy),direction="downwards") 我可以取出标签，但它们的顺序似乎不同。使用附加的顺序组件，您可以按正确的顺序取出标签 with(phy, labels[order]) # [1] "Maserati Bora" "Chrysler Imperial" "Cadillac Fleetwood" # [4] "

如果我们使用

ape

package从层次聚类中绘制系统图

phy <- hclust(dist(mtcars))
plot(as.phylo(phy),direction="downwards")

我可以取出标签，但它们的顺序似乎不同。

使用附加的

顺序组件，您可以按正确的顺序取出标签
