rotations

The goal of rotations is to provide tools for working with rotation data. A stable version (1.4) of the rotations package is available for download from CRAN. For Windows users, the current version (1.5) of rotations can be downloaded from GitHub. Mac users will need to download the repo, compile the C++ code and install.

Installation

remotes::install_github("stanfill/rotationsC", subdir = "rotations")

Example

This is a basic example which shows you how to solve a common problem:

Change log

• The Maxwell-Boltzmann distribution has been added: dmaxwell, pmaxwell and rmaxwell.
• Due to issue with the bessel functions, the Cayley distribution was previously used to approximate the matrix-Fisher distribution for large kappa. Now the Maxwell-Boltzmann distribution is used for kappa>200 and the approximation is far superior.
