[Spotted by Hank Stevens.]
Fixed.
o nncross.ppp, nncross.pp3
If 'iX' and 'iY' were given, some of the results were incorrect.
Fixed.

o package structure
The original 'spatstat' package has been divided into 7 sub-packages
(spatstat.utils, spatstat.data, spatstat.sparse,
spatstat.geom, spatstat.core, spatstat.linnet and spatstat).
The remaining 'spatstat' package requires all the other sub-packages.
Your existing code scripts should still work with minimal changes.
o overall speed
Changes have been made to the internal code of spatstat
which should accelerate computations involving large datasets.
o vcov.ppm, summary.ppm
Variance calculations now handle larger datasets
because they use sparse arrays, by default.

Accelerated.
o localpcf, localpcfinhom
New argument 'rvalue'.
o harmonise.im
The result belongs to class 'solist' and 'imlist'
so that it can be plotted.
o hyperframe, as.im.function
The formal default value of 'stringsAsFactors' has been changed
to 'NULL' to conform to changes in R. (The actual default value
is TRUE for R < 4.1.0 and FALSE for R >= 4.1.0)

New argument 'group' specifies that the points are divided into
several groups, and that relabelling is applied within each group.

so that it no longer depends on plot.linim, and is more efficient.
The formal argument list has been extended.

when the summary function produces NA or NaN or infinite values.

New argument 'clip'
BUG FIXES
o rLGCP, simulate.kppm
Simulation results for log-Gaussian Cox processes were incorrect
unless the pixel dimensions and pixel spacings were identical
on the horizontal and vertical axes. (If pixel dimensions were not
specified, then the results were incorrect whenever the Frame of the
simulation window was not a square.)
[Spotted by Tilman Davies.]
Fixed.
o crossdist.pp3
Results with periodic=TRUE were partially incorrect.
Fixed.

reduced-sample
(border correction) and Kaplan-Meier corrected estimates were calculated.
[Spotted by Gopalan Nair.]
Fixed.
o Lcross.inhom, Kcross.inhom, Kmulti.inhom
The option 'correction="none"' was accepted but ignored.
[Spotted by Corey Anderson.]
Fixed.

If the fitted model was effectively a Poisson process,
the result did not have attributes 'Lambda' and 'parents'
even when the user requested them.
Fixed.
o affine.owin

was too fine, leading to very large datasets.
Fixed.

of the result was too fine, leading to very large datasets.
Fixed.
o plot.ppp
For a point pattern in a binary mask window,

the points were coloured according to 'col', which was incorrect.
Fixed.

Fixed.
o Vmark
Crashed if normalise=TRUE when there was only one column of marks.
(Spotted by Pavel Fibich.)

Log message: geography/R-spatstat: import R-spatstat-1.63.2 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 2000 functions for plotting spatial data, exploratory data analysis, model-fitting, simulation, spatial sampling, model diagnostics, and formal inference. Many data types and exploratory methods are supported. Formal hypothesis tests of random pattern and tests for covariate effects 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 along with basic tools for model selection. |
