labeltodendro {labeltodendro} | R Documentation |
The function calls other internal functions to count labels, make a table of agglomerations and divisions, and gives a labclust
object.
labeltodendro(x,labels=NULL)
x |
A numeric matrix of integers with iterations in rows and labels in columns. Each row of x corresponds to a grouping. |
labels |
A vector of stings concering labels for each column of x ; The names of associated to the clustered subjects. |
The most frequent label will be used to search for agglomerations and divisioins and will be used for plotting and coloring the resulting dendrogram.
merge |
Returns a matrix of merges according to hclust format. |
height |
Gives heights of each branch of merge matrix. |
hcut |
Shows where the tree should be cut. |
