R中的树状图。如何按每个簇生成新表

库（mlbench）
图书馆（统计）
大学试试这个：

# your matrix dimensions have to match with the clustering results
# remove any columns from na.college, as you did for clustering
mat <- na.college[,-c(1:3)]

# select the data based on the clustering results
cluster_2 <- mat[which(groups==2),]

谢谢，但我还有一个问题。谢谢安德烈提出来！

# select the data based on the clustering results
cluster_2 <- mat[which(groups==2),]

# each list entry will correspond to the cluster number
clust_list <- lapply(sort(unique(groups)), function(x) mat[which(groups==x),])

# to retrieve i.e cluster 2:
cluster_2 <- clust_list[[2]]
