fingerprint - Functions to Operate on Binary Fingerprint Data
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.
