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

Hello R Users, I am trying to do a quadrat count defined by covariate properties in spatstat. I have read my elevation raster into R (from ascii) and converted to class "im" for use in spatstat. Now I have point data of class "ppp" which window is the same extent as the elevation image. I can conveniently plot the image and the points on the image as follows:

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. Thanks. neba [[alternative HTML version deleted]]

Hello, Somehow I cannot control my envelope plots on Spatstat package. I would like to plot an envelope with no legend and also I would 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
