In tourr: Tour Methods for Multivariate Data Visualisation
geodesic_info R Documentation
Calculate information required to interpolate along a geodesic path between
two frames.
Description
The methdology is outlined in
http://www-stat.wharton.upenn.edu/~buja/PAPERS/paper-dyn-proj-algs.pdf
and
http://www-stat.wharton.upenn.edu/~buja/PAPERS/paper-dyn-proj-math.pdf,
and the code follows the notation outlined in those papers:
Usage
geodesic_info(Fa, Fz, epsilon = 1e-06)
Arguments
Fa
starting frame, will be orthonormalised if necessary
Fz
target frame, will be orthonormalised if necessary
epsilon
epsilon used to determine if an angle is effectively equal
to 0
Details
p = dimension of data
d = target dimension
F = frame, an orthonormal p x d matrix
Fa = starting frame, Fz = target frame
Fa'Fz = Va lamda Vz' (svd)
Ga = Fa Va, Gz = Fz Vz
tau = principle angles
