spatstat是用于分析空间点模式数据的软件包。其功能包括探索性数据分析、模型拟合和模拟。它的设计是为了处理现实的数据集,包括不均匀的点模式,空间采样区域的任意形状,额外的协变量数据,和'标记'附加到点模式的点。spatstat的一个独特的功能是它的通用算法拟合点过程模型的点模式数据。该算法的接口是一个函数ppm,它与lm和glm非常类似。本文是spatstat的一般描述,并为新用户提供介绍。
spatstat is a package for analyzing spatial point pattern data. Its functionality includes exploratory data analysis, model-fitting, and simulation. It is designed to handle realistic datasets, including inhomogeneous point patterns, spatial sampling regions of arbitrary shape, extra covariate data, and `marks' attached to the points of the point pattern.A unique feature of spatstat is its generic algorithm for fitting point process models to point pattern data. The interface to this algorithm is a function ppm that is strongly analogous to lm and glm.This paper is a general description of spatstat and an introduction for new users.
