Hello all, I'm attempting to conduct spatial analysis of trees within a plot. I want to see if the trees are spatially correlated to soil characteristics, say pH, or moisture content. I think one way to do it is with mpl, however, my soil characteristics were not taken at exactly the same locations as my trees and further, the vectors aren't the same length. I'm getting the

This is a list with some libraries that I have been looking at. The idea is to discuss the advantages and disadvantages of adding some of these libraries to Xapian. If anyone knows another library that could be add to the list it would be great!

Our computing services people have recently reconfigured the Sun compilers structure on our network, and I can no longer install, on our Sun/Solaris machine, a certain package (spatstat) with which I am heavily involved. (The same problem may well pertain to other packages as well; I haven't yet experimented except with spatstat.) Strictly speaking I can ***install*** it, but when I try to

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 have gcc version 4.3.2, which should include gfortran and g++ - so I'm not sure what to do! Richard * Installing *source* package ?deldir? ... ** libs gfortran

Today I installed the newest R develepment branch R version 2.14.0 Under development (unstable) (2011-03-18 r54866) on FreeBSD 9.0-CURRENT (amd64). All seems fine so far. After that I updated my R packages with option 'checkBuilt=TRUE'. There are four packages (spatstat, pscl, adehabitatLT, adehabitatHR) which gives an error like this: Error in dyn.load(file, DLLpath = DLLpath, ...) :

Hi, I tried to install spatstat using: install.packages("spatstat", dependencies = TRUE, lib = "./R/i486-pc-linux-gnu-library/2.8") but got the following msg: --- Please select a CRAN mirror for use in this session --- <here i selected one mirror, and tried several mirrors) Loading Tcl/Tk interface ... done Warning message: In install.packages("spatstat",

My sincerest apologies, as this is a very elementary problem, but I have searched through archives and FAQs and on the web, and I am at the end of my own resources. I need to do analysis of a spatial point process occuring with four counties, using spatstat. I've had no trouble importing the shapefiles, but I can't seem to figure out what I need to do in order to use the boundary as an

Hola a toda la comunidad R, el siguiente problema tengo para hacer funcionar el paquete Spatstat. Tengo instalado R version 2.15.0, y Ubuntu 12.04 los cuales ya lo actualice. El paquete (spatstat) esta instalado pero puntualmente es problema es asi: / > library("spatstat") Loading required package: mgcv Error : .onLoad failed in loadNamespace() for ''Matrix'',

Hi R users, Working from a PC, I am trying to install the spatstat package on a Unix cluster. I created the following PBS file to send a job array: #!/bin/bash -ue #PBS -m ae #PBS -M my email #PBS -J 1-45 #PBS -A my username #PBS -N job name #PBS -l resources #PBS -l walltime cd $PBS_O_WORKDIR module load R/2.14.1 R CMD INSTALL -l /path/to/library spatstat R CMD BATCH

This is a cry for help. My apologies for taking up bandwidth with an issue that is not really on topic. But I really do want to acquire the requested information. In the course of preparing my PBRF (performance based research funds) portfolio for the upcoming PBRF exercise here in New Zealand, I have been advised that I should provide some estimate of the number of "active users" of

Greetings - Is it possible, inside .First.lib, to find out the version number of the package that is being loaded? If only one version of the package has been installed, we could scan the DESCRIPTION file, something like .First.lib <- function(lib, pkg) { library.dynam("spatstat", pkg, lib) dfile <- system.file("DESCRIPTION", package="spatstat")

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. I ultimately want to get something like this http://bg9.imslab.co.jp/Rhelp/R-2.4.0/src/library/spatstat/man/images/big_quadratcount_001.png http://bg9.imslab.co.jp/Rhelp/R-2.4.0/src/library/spatstat/man/images/big_quadratcount_001.png See

Dear All, I was searching through the spatstat manual in order to find a function to simulate a Poisson pattern only within a fixed radius (circular moving window) around individual points. If points are distributed heterogeneously over a large area this may help to only assess deviation from CSR within the window and thus does not require additional information on a covariate. I could not find

Dear Community I am at my wits end and seek advice. My wish is to plot coordinates (x,y in WGS84_UMTS for the ones interested) of sampling points. This I can do by the standard spatstat prodcedure via owin. I then try to add an image, which is a map/satellite photo in the background. Firstly Problem: With the current code, I can not get the edges of the image to match the boarders of the plot

Dear R users, I am using spatstat to analyze point patterns (tree locations). I would like to import the shapefile with the study area polygons (six total) into R and use it to create the window for the spatstat analysis. I do not simply want to use a rectangle because the study areas spread out over 40000 ha. Any suggestions would be greatly appreciated. Thanks, Charlotte Reemts Charlotte

I recently tried to install the latest version of spatstat, from CRAN, using the install.packages() function. It proceeded to install version 1.17-5 of spatstat, although the current version is 1.18-4. Checking the CRAN mirror that I used (New Zealand) via Firefox, I found that version 1.18-4 is indeed present on CRAN. I was able to download and install version 1.18-4 ``manually''

Hi, I know there are older threads discussing the quadratcount function in spatstat. Unfortunately, I could not find a solution to my problem there. I'm analyzing a point pattern in an irregular polygonal window. Both the window (an entire country) and the points are projected using WGS84. When I do quadratcount with only one quadrat for the entire country it holds all my 154 points:
