GNU R 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.
