Hi, > So there's a first question: can I use the plugin not only with 1.4.0 qgis, > but also in 1.6.0 (my current one) or even in 1.7.0?
yes you can, the installation of the dependencies for the plugins that rely on R is tricky under Windows especially, Under Vista/Seven. You need to use an "old" version of R (2.11, as rpy2 was not yet updated to cope with the changes in R >= 2.12), add the path to the R binaries in the Windows "path" environment variable, install the necessary libraries (see the plugin documentation) and, under Vista/Seven, copy the folder with the R libraries in another location. See this wiki page related to another plugin (based on R) that can help you understand the issues http://www.qgis.org/wiki/HomeRange_plugin I also noticed that many times under Windows, when installing R packages from the R console, it "fail" to install the requested package (but install its dependencies), so it is needed to re-issue the command.

Then check if you have fields (column names) with non ascii letters, if I remember correctly the plugin do not handle correctly such letters. cheers -- Giovanni -- _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
