RELEASE NOTES

spatstat 1.50-0

We thank Richard Cotton, Adrian Heyner, Abdollah Jalilian, Dominic Schuhmacher and Rasmus Waagepetersen for contributions.

spatstat is being split into several sub-packages, to satisfy the requirements of CRAN. This should not affect the user: existing code will continue to work in the same way. Currently there are two sub-packages, called ‘spatstat.utils’ and ‘spatstat’. Typing ‘library(spatstat)’ will load the familiar ‘spatstat’ package which can be used as before, and will silently import the ‘spatstat.utils’ package. The ‘spatstat.utils’ package contains utility functions that were originally written for ‘spatstat’: they were undocumented internal functions in ‘spatstat’, but are now documented and accessible in a separate package because they may be useful for other purposes. To access these functions, you need to type ‘library(spatstat.utils)’.

bw.pcf Bandwidth selection for pair correlation function. Original code contributed by Abdollah Jalilian and Rasmus Waagepetersen.
grow.box3 Expand a three-dimensional box.

as.owin Now refuses to convert a ‘box3’ to a two-dimensional window.
pixellate.ppp If the pattern is empty, the result is an integer-valued image (by default) for consistency with the results for non-empty patterns.
ppp If the coordinate vectors x and y contain NA, NaN or infinite values, these points are deleted with a warning, instead of causing a fatal error.
ppm Argument ‘interaction’ can now be a function that makes an interaction, such as Poisson, Hardcore, MultiHard.
pcf, pcfinhom New argument ‘close’ for advanced use.
runifpointx, rpoisppx New argument ‘drop’.
shapley, ponderosa In these installed datasets, the functions shapley.extra$plotit and ponderosa.extra$plotit have changed slightly (to accommodate the dependence on the package spatstat.utils).
kppm Improved printed output.

rMaternI, rMaternII If ‘win’ was a three-dimensional box of class ‘box3’, the result was a two-dimensional point pattern. [Spotted by Adrian Heyner.] Fixed.
rmhmodel.ppm, simulate.ppm Crashed when applied to a fitted Lennard-Jones model. [Spotted by Dominic Schuhmacher.] Fixed.
leverage.ppm, influence.ppm, dfbetas.ppm Crashed when applied to some hard-core models. Fixed.
”[.ppx” The format of the result was slightly malformed if exactly one point was selected. Fixed.
unmark.lpp, marks<-.lpp The result had class c(“lpp”, “lpp”, “ppx”) instead of c(“lpp”, “ppx”). Fixed.
