R包Nupoint提供了从点横断面调查中估计动物密度的工具，在该调查中，违反了点附近动物均匀分布的传统点横断面假设。它包括绘图、模型选择、拟合度测试和模拟工具。本文介绍了该程序包的主要特点，并通过对两种不同类型的调查数据集的应用说明了该程序包的使用。
The R package nupoint provides tools for estimating animal density from point transect surveys in which the conventional point transect assumption of uniform animal distribution in the vicinity of the point is violated. It includes tools for plotting, model selection, goodness‐of‐fit testing and simulation. This paper describes the main features of the package and illustrates its use by application to two different kinds of survey dataset.
