This package contains methods for working with orientation data, i.e.
data from SO(3). The basic abstract class is the
"orientation"; there are several concrete classes (with
constructions rotmatrix(), rotvector(),
eulerzyx(), eulerzxz(),
quaternion(), skewmatrix() and
skewvector()) storing different representations of
orientations.
Methods are defined to get the length of a vector of orientations, as well as to extract and replace elements, and to multiply orientations and raise them to real powers.
There are also utility functions rotation.distance(),
rotation.angle(), nearest.orthog() and
nearest.SO3().
There is a plotting method boat3d() to display
orientation data in a 3D plot, and a linear modelling function
orientlm().
