'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/9432944121Sat, 08 Jun 2024 23:43:47 GMTspatstat.random3.2-3.004successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.random[spatstat] spatstat.model 3.2-11.005Adrian.Baddeley@curtin.edu.au (Adrian Baddeley)Functionality for parametric statistical modelling and
inference for spatial data, mainly spatial point patterns, in
the 'spatstat' family of packages. (Excludes analysis of
spatial data on a linear network, which is covered by the
separate package 'spatstat.linnet'.) Supports parametric
modelling, formal statistical inference, and model validation.
Parametric models include Poisson point processes, Cox point
processes, Neyman-Scott cluster processes, Gibbs point
processes and determinantal point processes. Models can be
fitted to data using maximum likelihood, maximum
pseudolikelihood, maximum composite likelihood and the method
of minimum contrast. Fitted models can be simulated and
predicted. Formal inference includes hypothesis tests (quadrat
counting tests, Cressie-Read tests, Clark-Evans test, Berman
test, Diggle-Cressie-Loosmore-Ford test, scan test, studentised
permutation test, segregation test, ANOVA tests of fitted
models, adjusted composite likelihood ratio test, envelope
tests, Dao-Genton test, balanced independent two-stage test),
confidence intervals for parameters, and prediction intervals
for point counts. Model validation techniques include leverage,
influence, partial residuals, added variable plots, diagnostic
plots, pseudoscore residual plots, model compensators and Q-Q
plots.https://github.com/r-universe/spatstat/actions/runs/9432944262Sat, 08 Jun 2024 23:33:24 GMTspatstat.model3.2-11.005successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.model[spatstat] RandomFieldsUtils 1.2.5schlather@math.uni-mannheim.de (Martin Schlather)Various utilities are provided that might be used in

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
diagnostics, partial residuals, and added variable plots.https://github.com/r-universe/spatstat/actions/runs/9411170197Fri, 07 Jun 2024 03:24:19 GMTspatstat3.0-8.005successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstatreplicated.Rnwreplicated.pdfAnalysing Replicated Point Patterns in Spatstat2014-08-11 19:34:102021-12-12 10:08:34bugfixes.Rnwbugfixes.pdfBugs Fixed in Spatstat2018-07-27 05:41:232024-06-06 01:58:17datasets.Rnwdatasets.pdfDatasets Provided for the Spatstat Package2014-11-19 09:15:412023-02-01 05:49:45getstart.Rnwgetstart.pdfGetting Started with Spatstat2014-08-11 19:04:232021-12-12 10:08:34fv.Rnwfv.pdfGuide to Function Objects in Spatstat2023-07-21 05:53:522023-09-04 01:50:11shapefiles.Rnwshapefiles.pdfHandling shapefiles in the spatstat package2014-08-11 19:04:232024-03-20 16:38:52updates.Rnwupdates.pdfSummary of Recent Updates to the Spatstat Family2014-08-11 19:36:462024-06-06 01:58:17[spatstat] spatstat.linnet 3.1-5.004Adrian.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/9411169177Fri, 07 Jun 2024 03:21:56 GMTspatstat.linnet3.1-5.004successhttps://spatstat.r-universe.devhttps://github.com/spatstat/spatstat.linnet[spatstat] spatstat.explore 3.2-7.006Adrian.Baddeley@curtin.edu.au (Adrian Baddeley)Functionality for exploratory data analysis and
