Re: [R-sig-Geo] writeOGR error: problem with GDAL (libgdal1- 1.7.0)

Hi Augustin, I've encountered the same problem after an update of the rgdal-package. I have resolved the problem by removing the rgal-folder in the library and replacing it by an older version of November 2009. You can download that version of www.sovon.nl/temp/rgdal_nov_2009.zip Success! Hen

Re: [R-sig-Geo] problem saving spplot in a loop

Hi Alex, You have to assign the plot to a temporary variable (like tmp <- spplot(...)) and then use print(tmp1) to save it in the png-file so somethink like: tmp <- spplot(...) png(filename=...) print(tmp) dev.off() Succes! Henk ----- Henk Sierdsema

Re: [R-sig-Geo] need to create US map with colors by state

Hi Mark, The 'ASDAR'-book (Bivand et al, Applied Spatial Data Analysis with R http://www.asdar-book.org/) contains a lot of examples of desease mapping and modelling. From the website you can also download example data sets and scripts. Here is an (extended) example from page 91 onwards from

Hi Hans, Please have a look at paragraph 2.6 (page 41) on spatial polygons in the ASDAR-book. Here you will find an example of converting a shoreline into polygons. Henk Henk Sierdsema SOVON Vogelonderzoek Nederland / SOVON Dutch Centre for Field Ornithology Rijksstraatweg 178 6573 DG

Hi Juliane, I have found an Arcview3-extension that converts kml to shapes (http://arcscripts.esri.com/details.asp?dbid=14988) and that works fine. But it would like to solve the problem in the scripting-environment of R. Henk PS: the kml-files were made with Google Earth. Henk Sierdsema

Re: [R-sig-Geo] CODE for spatial logistic regression

Hi Rubén, Thanks for defining 'small' better. For me a dataset up to a thousand points is a small dataset, but for most people this is quite a big data set... Henk Henk Sierdsema SOVON Vogelonderzoek Nederland / SOVON Dutch Centre for Field Ornithology Rijksstraatweg 178 657

Re: [R-sig-Geo] CODE for spatial logistic regression

fact that you deny this in your second mail. So please extend more on the type of data you have and your aim. Next to geoRglm, which is only suitable for small datasets, you might also try regression-kriging. Is there by the way anyone who has experience with autoregressive models? Henk Henk
