Representations, conversions and display of 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 (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
,
nearest.SO3
.
There is a plotting method boat3d
to display orientation data
in a 3D plot, and a linear modelling function orientlm
.
Version 0.9
-Added CITATION file, dropped djmrgl support.
Versions 0.3 to 0.8
-Changes for CRAN compliance and minor corrections.
Version 0.2
-Added mean
and weighted.mean
.
-Made orientation
descend from vector
.
-Added [[
methods.
-Changed default look of boats.
-Made rotmatrix
etc. into conversion functions between
orientation types.
-Added eulerzxz
class.
-Added various parameters to boat3d
.
-Added orientlm
regression function plus transpose t()
method.
-Added rgl
and scatterplot3d
support to boat3d
function.
-Added skewmatrix
.
Version 0.1
-First release.
Plots require either the rgl
or scatterplot3d
package.
