### Description

Converts a nearest neighbor matrix into a list that can be used with the jarvisPatrick function.

### Usage

    fromNNMatrix(data, names = rownames(data))

### Arguments

`data` | A matrix containing integer valued indexes which represent items to be clustered. The index values contained in the matrix must be smaller than the number of rows in the matrix. Each row in the matrix represents one item and the columns are the nearest neighbors of that item.
