fingerprint (version 2.2)
Functions to operate on binary fingerprint data
Description
This package contains 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. Distances metrics are also available. Fingerprints
can be converted to Euclidean vectors (i.e., points on the unit hypersphere)i and
can also be folded using XOR. Arbitrary fingerprint formats can be handled via line
handlers. Currently handlers are provided for CDK, MOE and BCI fingerprint data.
