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.

`merge` |
Matrix with 2 columns. The Can also be the object returned by a call to |

`nclust` |
Number of clusters. |

Information about the clustering that has `nclust`

It is a list with the following elements:

`assign` |
Vector giving the assignment of items to clusters. |
