Plots the dendrogram of the entire heierarchical tree for a 'hmac' object starting from any specified smoothing level.
1 2 |
x |
The output of HMAC analysis. An object of class 'hmac'. |
mycol |
Colors used to represent different clusters. |
level |
The specified level that dendrogram starts. Default value is 1. |
n.cluster |
The specified number of clusters. If neither |
userclus |
If user provides membership, the tree colors the node according to this membership and the tree can be used for validation. |
sep |
It provides the distance between the lowest layer of nodes of the clusters. |
