Operations on the Riemannian manifold of symmetric, positive definite matrices (aka covariance matrices). Includes tools for estimation, interpolation, distance and mean calculations, and kernel methods.
A side project of mine for the last while has been the development of a pipeline for the statistical analysis of three dimensional motion trajectory data, including both position and rotation, using dual quaternions. The motion toolkit so far includes a package seathree, which implements basic operations on dual quaternions, and seacurve (in progress), implementing an R6 class representing a three dimensional motion trajectory as a smooth dual quaternion curve. Also included is a package motionImport which allows importing a motion trial data from the .exp files exported by the motion monitor system in our lab, though this is unlikely to be of use to anyone with a different system. More details can be found on the project page.
R package providing an updated and expanded version of the Population Value Decomposition (PVD) implemented by rTensor and proposed by Crainiceanu et al (2013).
