In many applications one may be interested in drawing inferences regarding the order of a collection of points on a unit circle. Due to the underlying geometry of the circle standard constrained inference procedures developed for Euclidean space data are not applicable. Recently, statistical inference for parameters under such order constraints on a unit circle was discussed in Rueda (2009); Fernández (2012). In this paper we introduce an R package called which provides a set of functions that can be used for analyzing angular data subject to order constraints on a unit circle. Since this work is motivated by applications in cell biology, we illustrate the proposed package using a relevant cell cycle data.
在许多应用中，人们可能有兴趣对单位圆上一组点的顺序进行推断。由于圆的基本几何形状，为欧几里得空间数据开发的标准约束推断程序并不适用。最近，鲁埃达（2009年）；费尔南德斯（2012年）讨论了单位圆上这种顺序约束下参数的统计推断。在本文中，我们介绍了一个名为 的R包，它提供了一组函数，可用于分析单位圆上受顺序约束的角度数据。由于这项工作是由细胞生物学中的应用推动的，我们使用相关的细胞周期数据来说明所提出的包。
