RELEASE NOTES
spatstat 1.631
21 February 2020
OVERVIEW

Enhancement to plot.linim

Fill missing pixel values by taking the nearest defined pixel value.

Minor improvements and bug fixes.

spatstat now requires spatstat.utils version 1.170.

Version nickname: ‘Made from recycled electrons’
NEW FUNCTIONS

is.linim
Tests whether an object belongs to class ‘linim’. 
nearestValue
Given a pixel image on a subset of a rectangle,
extend the image to the entire rectangle,
using the nearest welldefined pixel value.
SIGNIFICANT USERVISIBLE CHANGES

markconnect
Runs faster and handles much larger datasets. 
markvario
Runs faster and handles much larger datasets. 
markcorr, markconnect, markvario
The ‘weights’ can now be an expression to be evaluated,
or a function, or a pixel image, as well as a numeric vector. 
Smooth.ppp
The ‘weights’ can now be an expression to be evaluated,
or a function, or a pixel image, as well as a numeric vector. 
rpoislpp
If ‘lambda’ is a list of ‘linim’ or ‘linfun’ objects, then
the argument L can be omitted. 
plot.linim
New argument ‘fatten’ improves visual appearance when style=”colour”. 
plot.im, plot.owin
The coordinate axes will be plotted if axes=TRUE.
Axis labels xlab, ylab will be plotted if ann=TRUE. 
bugfixes
If sincedate=”all” or sinceversion=”all”, then all bugs will be listed. 
Jfox
New argument ‘warn.trim’ makes it possible to suppress repeated warnings. 
requireversion
New argument ‘fatal’
BUG FIXES

predict.rhohat, simulate.rhohat
When applied to a ‘rhohat’ object computed from
linear network data (lpp or lppm), there was a warning
about the lengths of vectors, and the results were incorrect.
Fixed. 
predict.rhohat, simulate.rhohat
Crashed when applied to a ‘rhohat’ object computed from multitype
linear network data (multitype lpp or lppm).
Fixed. 
Jfox
envelope() commands using the summary function ‘Jfox’
crashed sometimes with a message about illegal spacing of ‘r’ values.
Fixed. 
leverage, influence, dfbetas
Crashed when applied to an ‘ippm’ object in which
the irregular components of the score, but not the Hessian,
were provided by symbolic differentiation.
Fixed. 
parres
Crashed in rare circumstances, when the data did not contain
enough useable values to perform smoothing.
Fixed.
