fingerprint: Functions to operate on binary fingerprint data
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. 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.
