在本文中,我们介绍了旋转软件包,它为用户提供了模拟、分析和可视化三维旋转数据的能力。更具体地说,它包括四个用于模拟数据的常用分布、四个中心方位估计器、六个置信域估计程序和两种可视化旋转数据的方法。所有这些功能都可用于两种不同的旋转参数:三乘三矩阵和四元数。此外,还包括了说明旋转数据在实践中的使用的两个数据集。
In this article we introduce the rotations package which provides users with the ability to simulate, analyze and visualize three-dimensional rotation data. More specifically it includes four commonly used distributions from which to simulate data, four estimators of the central orientation, six confidence region estimation procedures and two approaches to visualizing rotation data. All of these features are available for two different parameterizations of rotations: three-by-three matrices and quaternions. In addition, two datasets are included that illustrate the use of rotation data in practice.
