 4  Converts a List of Fingerprints to a Matrix

 6\description{
 7    In general, fingerprint data is read from a file or obtained via
 8    calls to an external generator and the return value is a list of fingerprints.
 9    This function takes the list and returns a matrix having number of rows equal to 
10    the number of fingerprints and the number of columns equal to the length of
11    the fingerprint. Each element is 1 or 0 (1's being specified by the positions
12    in each fingerprint vector)
13}
14\usage{
15fp.to.matrix(fplist)
16}
17\arguments{
18    \item{fplist}{
19        A list structure with each element being an object of class
20	\code{fingerprint}. These will can be constructed by hand or
21	read from disk via \code{\link{fp.read}}
22    }
23}
24\value{
25A matrix with dimensions equal to \code{length(fplist), bit length)}
26where bit length is a property of the fingerprint objects in the list.
