similar to: help with spatstat ppp transformation data

Hi I want to extract the points from an object of type ppp. How can I do this? Rainer

I have used smooth.ppp in spatstat to create a smoothed surface plot based on randomly selected depths across a lake (as marks). I wonder if based on the smoothed surface plot if I can calculate the average depth for each 10x10 grid square across the lake. I can't see any obvious way of doing this and would appreciate some pointers. Many thanks, Graham [[alternative HTML version

Dear all, I'm working with two point patterns (ppp) in spatstat. I turned one of them into a spatial covariate (im) object. After that, I used this im object to fit a Poisson model for the second point pattern, using the covariate layer from the first one. In R, the whole thing looks somewhat like this: my_first.im <- as.im(my_first.ppp) test.ppm <- ppm (my_second.ppp, ~my_first,

Hi everybody: Does anyone know how I can change geodesic coordenates into UTM ones?

Hi R-Users, I have plotted a region whose polygon coordinates are given in shp format ED50 UTM (zone=30) ) using "readShapePoly" in library(maptools). Now I need to plot a set of points in that region (my.dataframe, with X and Y geographic coordinates), which have been read using GPS in Longitud-Latitud form (using WGS84 system), so I first need to convert these Longitud-Latitud data

I upgraded to R version 2.6.0 yesterday; now I find that I can't load spatstat. I re-installed spatstat (that part seemed to work without complaint) but when I execute > library(spatstat) I get the error message Error in dyn.load(file, ...) : unable to load shared library '/Users/rturner/Rlib/spatstat/libs/ i386/spatstat.so':

Hi all, I am trying to install Spatstat on OpenSUSE 11.1. install.packages("spatstat", dependencies = TRUE) fails on the basis of various compiler packages (full message below).

I'm testing some different formulations of pairwise interaction point processes in Spatstat (version 1.11-6) using R 2.5.0 on a Windows platform and I wish to simulate them using the Metropolis-Hastings algorithm implemented with Spatstat. Spatstat utilizes Fortran77 code with the preprocessor RatFor to do the Metropolis-Hastings MCMC, but the Makefile is more complicated than any I have

Hello, I am trying to plot a quadratcount object over a ppp object in the spatstat package.

Fellow Users, In Spatstat, if you have a ppp object with, say 100 points, how do you create another ppp containing a random selection, N, of the original? You can tell the function 'rthin' to make a sub-selection of points, i.e. "every point is removed with probability 0.5" but you CAN'T set N exactly... I'm sure this should be easy... Ta!

spatstat 1.11-0 Version 1.11-0 of package 'spatstat' is now available. Spatstat is a package for the analysis of spatial data, mostly point pattern data. See <www.spatstat.org> Important changes in version 1.11-0: New format for ppm objects (objects in old format are still handled). More stringent checking of function arguments. Improved handling of pixellation effects.

Dear r-help, I would like to use the 'ppm' function of the 'spatstat' package to fit a Strauss inhibition model. I understand that I can specify a parametric model for the "background" trend, but how would I specify a trend which is estimated using a Kernel density smoother? In particular, I would like to use the 'kde' function of the 'ks' package to

Hi all, I'm using spatstat to investigate the spatial structure of an arid shrub population. The first-order intensity of my data does not appear to be homogenous, so I would like to use inhomogeneous techniques. I realise there is a inhomogeneous K-function available in spatstat, but there doesn't not appear to be one for the pair-correlation function (O-ring statistic). As such I was
