rotations

The goal of rotations is to provide tools for working with rotation data. A stable version (1.6.3) of the rotations package is available for download from CRAN. For Windows users, the current version (1.6.4) 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:

library(rotations)
## basic example code

Change log

  • Dropped interactive option for plotting because sphere plot was going to be removed from CRAN
