Question

我使用R来聚类一个我称之为'tissuedata'的矩阵。我有一个使用以下代码生成的hclust对象：

    TissueDist<-dist(tissuedata, method="euclidean")
    TissueClust<-hclust(TissueDist, method='complete')

现在我想打印出TissueClust中的行名，同时保留聚集行的顺序。有什么建议吗？

以下是'tissuedata'矩阵可以包含的示例：

                                          Brain      Bone    Breast      Lung Ovary  Pancreas      HeLa

我不确定我是否理解这个问题.....

# $labels gives orginal ordering form matrix
TissueClust$labels

# $order gives the permutation of the original observations
# see ?hclust detail section
TissueClust$order

# not sure, but are you looking for this?
TissueClust$labels[c(TissueClust$order)]
