Hello UseRs, I need help on how to plot several raster images (such as those obtained from a kernel-smoothed intensity function) in a layout such as that obtained from the lattice package. I would like to obtain something such as obtained from using the "levelplot" or "xyplot" in lattice. I currently use: >par(mfrow=c(3,3) to set the workspace, but the resulting plots

...uld like to label the plot as such: >plot(envelope(data, nsim=39, main="My K Plot", legend=FALSE, xlab="Distance") But somehow the "main", "legend" and "xlab" calls do not have any effect on the plot. Can someone help me out? Thanks -- Neba, Funwi-Gabga Universitat Jaume I Castellon, Spain. [[alternative HTML version deleted]]

...unt.ppp(points, tess = aspect.tess) : Tessellation does not contain all the points of X I have checked and the extent of the tessellated elevation image is different from the original elevation image (smaller). Is there anything I am missing here? Please any help will be appreciated. -- Neba, Funwi-Gabga Universitat Jaume I Castellon, Spain. [[alternative HTML version deleted]]

Hello, I have fitted a Poisson Process model in spatstat using >fit1<-ppm(points, ~elevation, covariates=list(elevation=elevation.im)) This far, everything went well, but I try to simulate the fitted model using the function: >sim1<-rmh(fit1) But I get the error message: "Extracting model information...Evaluating trend...done. Checking arguments..determining simulation

Hello group, Can someone please put me through how to estimate the nuisance parameters (Saturation parameter and radius) for the Geyer saturation process? It seems quite confusing to me how these parameters are achieved, but they are very important in determining the interaction between points in a point process. I am using Spatstat package.
