random.fingerprint

The length of the fingerprint, that is, the total number of bits.
 Must be a positive integer.

nbit

How many positions should be set to 1

A utility function that can be used to generate binary fingerprints
 of a specified length with a specifed number of bit positions
 (selected randomly) set to 1. Currently bit positions are selected uniformly

logic

Functions to manipulate binary fingerprints
of arbitrary length. A fingerprint is represented by an object of S4 class 'fingerprint'
which is internally represented a vector of integers, such
that each element represents the position in the fingerprint that is set to 1.
The bitwise logical functions in R are overridden so that they can be used directly
with 'fingerprint' objects. A number of distance metrics are also
available (many contributed by Michael Fadock). Fingerprints
can be converted to Euclidean vectors (i.e., points on the unit hypersphere) and
can also be folded using OR.  Arbitrary fingerprint formats can be handled via line
handlers. Currently handlers are provided for CDK, MOE and BCI fingerprint data.
