Full_Name: Carsten Dormann Version: 1.4.0 OS: Windows 2000 Submission from: (NULL) (192.171.129.9) Hello, using the function xyplot I repeatedly had R crashing. One example is from the book of Mick Crawley (Stat. Computing in Splus), where the commandline reads: xyplot(Weight~Age|Genotype, pch=16) I also had the same phe...

..., or alternative implementation frameworks (e.g. sage) Before I start programming (in C inefficiently myself), I would like to seek your advice. Any help (also implementations in other languages/software as long at it is GPL or alike) would be appreciated! Cheers, Carsten -- Dr. Carsten F.

Hello, I''m working through the tutorial, and I''ve run into a little snag. In the first part of the tutorial, the destroy link is not working correctly. I can''t figure out where I goofed. Removing :confirm doesn''t seem to resolve the issue. Thanks, Randy. development.log ----->8----- Processing AdminController#destroy (for 127.0.0.1 at 2006-04-27

...= binomial(link = "logit"), data = Birds) The model seems to run fine. However, when I compare the results of this model and the residual spread against the same model but without the correlation function, there is absolutely no difference at all. I am somewhat confused by this as both Dormann et al. 2007 and Bivand et al. 2008 have suggested the use of the glmmPQL function to model binomial data with spatial autocorrelation and random effects. Therefore I am wondering if anyone knows why this has occurred and secondly I am wondering if the correlation function does indeed work outside...

Hi Everyone, I am doing a project based on "Spatially Lagged Predictor Variable Models", I would like to know which package in R would execute this model. Also, I am new to this field of spatial statistics. Any suggestions for a good book on spatial regression analysis would be appreciated. Thanks Again. Cheers Arun -- View this message in context:

Dear all, I have been using the function gls in the package nlme in R to fit some spatial regressions (as described in Dormann et al.). However, I have been struggling trying to find a way to calculate a measure of effect size from these models, so I wanted to know if any of you had an idea on how to do this. More precisely, I am producing a multiple model with an exponential correlation structure: spatial.gls<-gls...

Hi, I have collected data on trees from 5 forest plots located within the same landscape. Data within the plots are spatially autocorrelated (calculated using Moran's I). I would like to do a ANCOVA type of analysis combining these five plots, but the assumption that there is no autocorrelation in the residuals is obviously violated. Does anyone have any ideas how to incorporate these spatial

Hi, I have spatially autocorrelated data (with a binary response variable and continuous predictor variables). I believe I need to do an autologistic model, does anyone know a method for doing this in R? Many thanks C Bell
