I am trying to create a PPP in spatstat using my study area (a large polygon made up of individual polygons) from a shape file from GIS. I have been ...
Is there any way to fit a spatial statistical model to 3d data in spatstat? I have tried using the functions such as ppm and kppm but they are not wo ...
I am generating a landscape pattern that evolves over time. The problem with the code is that I have clearly defined a window for the object bringing ...
I would like to use envelope simulation on a list of kppm objects. I have a point dataset that is in a grid pattern. I would like to shift each point ...
My goal is to analyse simple point patterns on linear networks with respect to Euclidean distance instead of shortest-path distance implemented in lin ...
Anyone have advice for retaining (or appending) attributes from a Spatial Polygons Data Frame after conversion to an owin object for pattern analysis ...
I recently dabbled a bit into point pattern analysis and wonder if there is any standard practice to create mark correlation structures varying with t ...
I had a raster with values from 0 to 0,3 which I transformed into an image. Then i gave all values <=0.3 the value 1. I thought it makes it easier ...
I have been using lppm (point pattern on a linear network) on spatstat with bunch of covariates and fitting a log-linear model but I couldn't see how ...
I am making a series of plots from a point pattern (PPP) with the density (kernel) function. I would like that the maximum plotted number is 200 in al ...
On pp. 73-74 in "“Stationary” point processes are uncommon on linear networks"* by Adrian Baddeley, Gopolan Nair, Suman Rakshit, and Greg McSwiggan, t ...
I converted a raster to an image and wanted to plot it. However, I then get the following error: I've already tried to find this error with help(pl ...
I have a dataset with several groups, where I want to calculate a median value for each group using dplyr. The data are weighted, and the weights need ...
I really really need some advice. I have a Raster with many pixels. Each pixel has one value. Now I want to do a spatial analysis of these pixels. I w ...
i'm trying to use the Kest function (and many other in the spatstat package). i have made a ppp point pattern data set (ppp.1) summary (ppp.1) Plana ...
I'm working with spatstat 2.3-4 in R 4.1.0 on a 64bit windows 10 pro machine. Recently I ran into the integer-overflow error while using Kcross with a ...
I try to install from github spatstat.explore and spatstat.model but this does not work because spatstat.random 2.2.0.7 is needed. I cannot find the l ...
Is there any way to use reference bandwidth selection for kernel smoothing in spatstat package? ...
I am using spatstat to build point process models using the ppm function but I have problems in validation, when I use the residual plot parres to und ...
