# Euclidean Representation of Binary Fingerprints

### Description

Ordinarily, a binary fingerprint can be considered to represent a corner of a nD hypercube. However in many cases using such a representation can lead to a very sparse space. Consequently one approach is to convert the fingerprint so that it represents points on a nD unit hypersphere.

The resultant fingerprint is then a nD coordinate.

### Usage

1 | ```
euc.vector(fp)
``` |

### Arguments

`fp` |
An object of class |

### Value

A numeric of length equal to the bit length of the fingerprint. The result corresponds to a unit vector for a point on the nD hypersphere
