Agglomerative hierarchical clustering procedures typically produce
a list of the clusters merged at each stage of the clustering.
cluinf
uses this list to construct arrays that explicitly show
which cluster a given data point belongs to, and which data points belong
to a given cluster.
1 
merge 
Matrix with 2 columns. The ith row contains the labels of the clusters merged at the ith merge. Can also be the object returned by a call to 
nclust 
Number of clusters. 
Information about the clustering that has nclust
clusters.
It is a list with the following elements:
assign 
Vector giving the assignment of items to clusters. 
list 
List with 
num 
Vector of length
