 4  Generate Randomized Fingerprints

 6\description{
 7  A utility function that can be used to generate binary fingerprints
 8  of a specified length with a specifed number of bit positions
 9  (selected randomly) set to 1. Currently bit positions are selected uniformly
10}
11\usage{
12random.fingerprint(nbit,on)
13}
14\arguments{
15    \item{nbit}{
16      The length of the fingerprint, that is, the total number of bits.
17      Must be a positive integer.
18    }
19    \item{on}{
20      How many positions should be set to 1
21      }

23\value{
24An object of class \code{fingerprint}
