euc.vector {fingerprint} | R Documentation |
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.
euc.vector(fp)
fp |
An object of class fingerprint .
|
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
