Description Usage Arguments Details Value Author(s) Examples

To execute complete agglomerative hierarchical clusterization algorithm choosing distance and approach type.

1	agglomerativeHC(data, distance, approach)

`data`	could be a numeric vector, a matrix or a numeric data frame. It will be transformed into matrix and list to be used.
`distance`	is a string. It chooses the distance to use.
`approach`	is a string. It chooses the approach to use.

This function is the main part of the agglomerative hierarchical clusterization method. It executes the theoretical algorithm step by step.

1 - The function transforms data in useful object to be used.

2 - It creates the clusters.

3 - It calculates a matrix distances with the clusters created applying distance and approach given.

4 - It chooses the distance value and gets the clusters.

5 - It groups the clusters in a new one and updates clusters list.

6 - It repeats these steps until an unique cluster exists.

R object with a dendrogram, the grouped clusters and the list with every cluster.
