Hello, I'm using memisc to output regression results to tables and latex. My problem is that the output that Latex needs must be in between $ $ so that it is read as formula but memisc does not output the result...

Omar, I think that the following document will be of help: https://cran.r-project.org/web/packages/dismo/vignettes/sdm.pdf It is a gentle and practical introduction to raster: both data handling and regression. It is about species...

With levelplot I would like to combine fitted values and "raw" values in one plot. The surface should be based on fitted values and on top of those I would like distinguisable points based on the raw data with a...

Dear Roger and others, Using the impacts function in spdep to calculate distributions (on the regression parameters from the spatial lag model) I encountered the following problem: when there is only one exogenous predictor in the model the impacts function...

Roger Bivand mentions LeSage's matlab toolbox (http://www.spatial-econometrics.com/), including very clear manuals with theory. I am unable to judge the theoretical validity of the routines but I experienced that I was able to estimate parameters of...

Hi all, I have a polygon shapefile with a column in the attribute table denoting class (in my case "habitat"). I construct a gridded SpatialPolygonsDataFrame. For each gridcell I'd like to be able to obtain the surface of each...

Thank you Martin, It turned out that my problem was that I used underscores "_" in my variable names. No problem for R, but Latex didn't like it. Kind regards, Eelke Martin Elff wrote: > > On Monday 25 August 2008 (15...

Hi, I think you might be interested in the function lagsarlm in the spdep package for a maximum likelihood way to estimate the spatial autoregressivemodel for continuous (normal) data. spdep has all kinds of ways to calculate the spatial weight...

Hi Holly, Could you provide some insight into your int object. Does it happen for all i? My first guess is that your matrix 'int' might not be what you expect; try: grid[int[,i],] and see whether it is...

Thank you Paul, I did indeed get more advice from Tomislav Hengl, the same as yours. And given the reliability of the (through kriging) predictions of the auxiliary variable it indeed makes most sense as you advice also. Cheers, Eelke...
