Support for Orientation Data.
orientlib: Support for Orientation Data
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()
.
