I am looking for online courses to learn Spatial Statistics using R. Statistics.com is offering an online course in December on the same topic but that schedule doesn't suit mine. Are there any other similar modes for learning spatial statistics using R??? Can someone please advice??? Thank you. Ravi -- View this message in context:

Dear Aaron, I am really a tool user and not a tool maker (actually an ecologist doing some biostatistics)... so, I take the liberty of sending a copy of this e-mail to the r-help list where capable computer persons and true statisticians may provide more relevant information and also to Paulo Ribeiro and Peter Diggle, the authors of geoR.. I really feel that your huge matrix cannot be

Hello to everybody ! I don't have a question directly connected with R, but it takes starting point from the use of the R function Krig for kriging interpolation and from the idea of making a different implemetation of the function for my purposes. Doas anyone know where can I find free C or C++ codes of kriging ? As always, thanks a lot in advance, Paola.

System info: Linux slackware R Version 1.5.1 (2002-06-17) ESS 5.1.21 Emacs 21.2.1 ------------------- Colleagues Thanks very much for advice. I was not aware of the Fields package (although I've been using Geostat and Spatial). The image.plot() function in Fields does a lovely job, with an added bonus of fixing the problem I was having of balancing the number of colour levels with the

R Experts, I'm looking for some help with the geoR package. I'm trying to krig some data without using a global neighborhood. I would like to set my moving neighborhood to a distance, say 100 meters, where I know my data is spatially correlated. I have tried the ksline function, but that only allows my moving neighborhood to be set to a number of data points. But, since my data

...t the expression found in the documentation is also that found in Pinheiro and Bates 2000 (Table 5.2, p. 232). It's not listed in the errata for the first printing http://cm.bell-labs.com/cm/ms/departments/sia/project/nlme/MEMSS/Errata ; I have the second printing. (I haven't dug out my geostats books to check this, but found at least one paper that cites the "correct" (1/(1+(d/r)^2) formula -- see below cheers Ben Bolker @ARTICLE{Ekstrom+2005, author = {Ekstr{\o}m, Claus T. and Bak, S{\o}ren and Rudemo, Mats}, title = {Pixel-level Signal Modelling with Spatial Correla...

I notice compositions was removed on CRAN, that's one I want to try out. I downloaded the last tarball, the build output doesn't look that bad.

Hi, all, Have anyone used kringing included in R? How is it? Does it handle anisotropy data well? How does it compare with Kriging in Arc/Info? or other geostatistics software customized to do kriging or other geostatistics functions? I tried Easykriging, a geostatistics tool developed for Matlab. It has very nice GUI, but it does not provide library which i can call in my programs. so it is

Hola buenos días: Hace algún tiempo mandé una duda que sobre fichero tipo shapefile que publica el Instituto Geográfico Nacional de España y que detallo en el word Duda_sobre_shp. El tema es que al final no obtuve respuesta (es cierto que lo mandé en Agosto y en esa fechas entiendo que sea normal, por tanto por recomendación de un conocido vuelvo de nuevo a remitir la cuestión) Como no podía

Dear All, Does anyone know of any GIS packages for R? I know that there are GIS facilities for S-Plus (eg Arc Info), and am looking for freeware equivalents.
