# RELEASE NOTES ## spatstat 1.63-1 ### 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 1.17-0. * 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 well-defined pixel value. ### SIGNIFICANT USER-VISIBLE 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 1. 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. 2. predict.rhohat, simulate.rhohat Crashed when applied to a 'rhohat' object computed from *multitype* linear network data (multitype lpp or lppm). Fixed. 3. Jfox envelope() commands using the summary function 'Jfox' crashed sometimes with a message about illegal spacing of 'r' values. Fixed. 4. 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. 5. parres Crashed in rare circumstances, when the data did not contain enough useable values to perform smoothing. Fixed.
