CHANGES IN spatstat.linnet VERSION 2.3-2 OVERVIEW o 'spatstat.linnet' now depends on 'spatstat.random'. SIGNIFICANT USER-VISIBLE CHANGES o package dependence 'spatstat.linnet' now depends on the new package 'spatstat.random'. CHANGES IN spatstat.linnet VERSION 2.3-1 OVERVIEW o More control over resolution of 'linim' objects. o Improved documentation. o Minor improvements and bug fixes. SIGNIFICANT USER-VISIBLE CHANGES o as.linim.default, as.linim.linfun New argument 'nd' o integral.linfun New argument 'nd' o rjitterlpp, rjitter.lpp The function 'rjitterlpp' has been renamed 'rjitter.lpp' and is now a method for the generic 'rjitter'. o rjitterlpp This function still exists, but is now deprecated in favour of 'rjitter.lpp'. BUG FIXES o rjitterlpp The argument 'radius' was interpreted as a fraction of segment length rather than an absolute distance. Fixed. CHANGES IN spatstat.linnet VERSION 2.3-0 OVERVIEW o We thank Suman Rakshit, Greg McSwiggan and Marc Schneble for contributions. o Sufficient Dimension Reduction on a linear network. o Perspective-view plots of linfun and linim objects. o Bug fix to Math.linim o Minor additions. NEW FUNCTIONS o sdr.lpp Sufficient Dimension Reduction on a linear network. [Contributed by Suman Rakshit.] o persp.linfun, persp.linim Perspective-view plots of functions on a linear network (class linim) and images on a linear network (class linfun). [Written by Adrian Baddeley and Greg McSwiggan.] SIGNIFICANT USER-VISIBLE CHANGES o response.lppm Method for 'response' for fitted point process models on a network. BUG FIXES o Math.linim If 'Z' was a pixel image on a network (class 'linim') and 'v' was a single number, then 'Z/v' was a pixel image (class 'im') instead of a pixel image on a network (class 'linim'). [Spotted by Marc Schneble.] Fixed. o bw.voronoi Printed output stated that the cross-validation criterion was minimised instead of maximised. CHANGES IN spatstat.linnet VERSION 2.2-1 OVERVIEW o Minor changes to satisfy CRAN. CHANGES IN spatstat.linnet VERSION 2.2-0 OVERVIEW o Extensions to rhohat.lpp and rhohat.lppm. o Internal bug fixes. SIGNIFICANT USER-VISIBLE CHANGES o rhohat.lpp, rhohat.lppm New option (smoother='piecewise') computes a piecewise-constant estimate of rho(z). o rhohat.lpp, rhohat.lppm The result now includes the 'average' intensity rho. CHANGES IN spatstat.linnet VERSION 2.1-1 OVERVIEW o Tweak to satisfy the package checker. CHANGES IN spatstat.linnet VERSION 2.1-0 OVERVIEW o We thank Andrea Gilardi for contributions. o Bug fix in density.lpp o Improvement to densityEqualSplit o New function for jittering point patterns on a network. o Function renamed. NEW FUNCTIONS o rjitterlpp Apply random displacements to the points on a linear network. o densityHeat.lpp Diffusion kernel estimation of intensity on a linear network. (formerly known as 'densityHeatlpp' and 'densityHeat', this is now a method for the new generic 'densityHeat') SIGNIFICANT USER-VISIBLE CHANGES o densityEqualSplit New arguments 'at' and 'leaveoneout' for consistency with other functions. o densityHeat The function formerly known as 'densityHeat' or 'densityHeatlpp' is now renamed 'densityHeat.lpp' and is a method for the generic 'densityHeat'. o density.lpp Accelerated when the pattern contains duplicated points. BUG FIXES o density.lpp The result had the wrong length if 'x' contained duplicated points when 'weights' were given and 'at="points"'. [Spotted by Andrea Gilardi] Fixed. CHANGES IN spatstat.linnet VERSION 2.0-0 OVERVIEW o We thank Andrea Gilardi for contributions. o Function renamed. o Bug fix in density.lpp SIGNIFICANT USER-VISIBLE CHANGES o densityHeat 'densityHeat' has been temporarily renamed 'densityHeatlpp', to prevent errors in the package checking process. o [.linim Accelerated. BUG FIXES o deviance.lppm, pseudoR2.lppm Results were completely incorrect, due to a coding error. Fixed. o density.lpp Crashed if 'weights' were given and 'x' contained duplicated points. [Spotted by Andrea Gilardi] Fixed. o Lcross.inhom, Kcross.inhom, Kmulti.inhom The option 'correction="none"' was accepted but ignored. [Spotted by Corey Anderson.] Fixed. o simulate.rhohat Crashed when applied to rhohat objects computed from data on a linear network. Fixed. CHANGES IN spatstat.linnet VERSION 1.65-9 OVERVIEW o Minor internal changes. CHANGES IN spatstat.linnet VERSION 1.65-8 OVERVIEW o Function renamed. SIGNIFICANT USER-VISIBLE CHANGES o densityHeat 'densityHeat' has been renamed 'densityHeat.lpp'. CHANGES IN spatstat.linnet VERSION 1.65-7 OVERVIEW o Tweaks to satisfy CRAN. CHANGES IN spatstat.linnet VERSION 1.65-1 OVERVIEW o Added NEWS file. CHANGES IN spatstat.linnet VERSION 1.65-0 OVERVIEW o Package initialised at version 1.65-0 SIGNIFICANT USER-VISIBLE CHANGES o spatstat.linnet The package 'spatstat.linnet' has been created from a subset of the code in the original 'spatstat' package version 1.65-0. It contains the functionality for statistical analysis of spatial data on a linear network. For an overview, see help("spatstat.linnet-package") o Execution The 'spatstat.linnet' package is slightly faster than the corresponding code in the 'spatstat' package, because the procedure for calling internal C functions has been streamlined.
