'spatstat' family of packages. Generates random spatial
patterns of points according to many simple rules (complete
spatial randomness, Poisson, binomial, random grid, systematic,
cell), randomised alteration of patterns (thinning, random
shift, jittering), simulated realisations of random point
processes including simple sequential inhibition, Matern
inhibition models, Neyman-Scott cluster processes (using
direct, Brix-Kendall, or hybrid algorithms), log-Gaussian Cox
processes, product shot noise cluster processes and Gibbs point
processes (using Metropolis-Hastings birth-death-shift
algorithm, alternating Gibbs sampler, or coupling-from-the-past
perfect simulation). Also generates random spatial patterns of
line segments, random tessellations, and random images (random
noise, random mosaics). Excludes random generation on a linear
network, which is covered by the separate package
'spatstat.linnet'.https://github.com/r-universe/spatstat/actions/runs/7028069408Wed, 29 Nov 2023 04:17:42 GMTspatstat.random3.2-2successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.random[spatstat] spatstat.explore 3.2-5.001Adrian.Baddeley@curtin.edu.au (Adrian Baddeley)Functionality for exploratory data analysis and nonparametric analysis of

Methods include quadrat counts, K-functions and their simulation envelopes, nearest neighbour distance and empty space statistics, Fry plots, pair correlation function, kernel smoothed intensity, relative risk estimation with cross-validated bandwidth selection, mark correlation functions, segregation indices, mark dependence diagnostics, and kernel estimates of covariate effects. Formal hypothesis tests of random pattern (chi-squared, Kolmogorov-Smirnov, Monte Carlo, Diggle-Cressie-Loosmore-Ford, Dao-Genton, two-stage Monte Carlo) and tests for covariate effects (Cox-Berman-Waller-Lawson, Kolmogorov-Smirnov, ANOVA) are also supported.https://github.com/r-universe/spatstat/actions/runs/6913077010Sat, 18 Nov 2023 08:45:45 GMTspatstat.explore3.2-5.001successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.explore[spatstat] spatstat.linnet 3.1-3.002Adrian.Baddeley@curtin.edu.au (Adrian Baddeley)Defines types of spatial data on a linear network
and provides functionality for geometrical operations,
data analysis and modelling of data on a linear network,
in the 'spatstat' family of packages.
Contains definitions and support for linear networks, including creation of networks, geometrical measurements, topological connectivity, geometrical operations such as inserting and deleting vertices, intersecting a network with another object, and interactive editing of networks.
Data types defined on a network include point patterns, pixel images, functions, and tessellations.
Exploratory methods include kernel estimation of intensity on a network, K-functions and pair correlation functions on a network, simulation envelopes, nearest neighbour distance and empty space distance, relative risk estimation with cross-validated bandwidth selection. Formal hypothesis tests of random pattern (chi-squared, Kolmogorov-Smirnov, Monte Carlo, Diggle-Cressie-Loosmore-Ford, Dao-Genton, two-stage Monte Carlo) and tests for covariate effects (Cox-Berman-Waller-Lawson, Kolmogorov-Smirnov, ANOVA) are also supported.
Parametric models can be fitted to point pattern data using the function lppm() similar to glm(). Only Poisson models are implemented so far. Models may involve dependence on covariates and dependence on marks. Models are fitted by maximum likelihood.
Fitted point process models can be simulated, automatically. Formal hypothesis tests of a fitted model are supported (likelihood ratio test, analysis of deviance, Monte Carlo tests) along with basic tools for model selection (stepwise(), AIC()) and variable selection (sdr). Tools for validating the fitted model include simulation envelopes, residuals, residual plots and Q-Q plots, leverage and influence diagnostics, partial residuals, and added variable plots.
Random point patterns on a network can be generated using a variety of models.https://github.com/r-universe/spatstat/actions/runs/6717301805Wed, 01 Nov 2023 08:12:23 GMTspatstat.linnet3.1-3.002successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.linnet[spatstat] spatstat 3.0-7Adrian.Baddeley@curtin.edu.au (Adrian Baddeley)Comprehensive open-source toolbox for analysing Spatial
Point Patterns. Focused mainly on two-dimensional point
patterns, including multitype/marked points, in any spatial
region. Also supports three-dimensional point patterns,
space-time point patterns in any number of dimensions, point
patterns on a linear network, and patterns of other geometrical
objects. Supports spatial covariate data such as pixel images.
Contains over 3000 functions for plotting spatial data,
exploratory data analysis, model-fitting, simulation, spatial
sampling, model diagnostics, and formal inference. Data types
include point patterns, line segment patterns, spatial windows,
pixel images, tessellations, and linear networks. Exploratory
methods include quadrat counts, K-functions and their
simulation envelopes, nearest neighbour distance and empty
space statistics, Fry plots, pair correlation function, kernel
smoothed intensity, relative risk estimation with
cross-validated bandwidth selection, mark correlation
functions, segregation indices, mark dependence diagnostics,
and kernel estimates of covariate effects. Formal hypothesis
tests of random pattern (chi-squared, Kolmogorov-Smirnov, Monte
Carlo, Diggle-Cressie-Loosmore-Ford, Dao-Genton, two-stage
Monte Carlo) and tests for covariate effects
(Cox-Berman-Waller-Lawson, Kolmogorov-Smirnov, ANOVA) are also
supported. Parametric models can be fitted to point pattern
data using the functions ppm(), kppm(), slrm(), dppm() similar
to glm(). Types of models include Poisson, Gibbs and Cox point
processes, Neyman-Scott cluster processes, and determinantal
point processes. Models may involve dependence on covariates,
inter-point interaction, cluster formation and dependence on
marks. Models are fitted by maximum likelihood, logistic
regression, minimum contrast, and composite likelihood methods.
A model can be fitted to a list of point patterns (replicated
point pattern data) using the function mppm(). The model can
include random effects and fixed effects depending on the
experimental design, in addition to all the features listed
above. Fitted point process models can be simulated,
automatically. Formal hypothesis tests of a fitted model are
supported (likelihood ratio test, analysis of deviance, Monte
Carlo tests) along with basic tools for model selection
(stepwise(), AIC()) and variable selection (sdr). Tools for
validating the fitted model include simulation envelopes,
residuals, residual plots and Q-Q plots, leverage and influence
