[...] Thanks very much, this is the information needed, that there are no fields. It appears that at least in this driver, readOGR() needs to be able to return a geometry-only object, or to create a GID column in the data.frame. I'll let you know when I've committed to R-forge, and will be very grateful if you can check out the source package, install, and test whether the changes have helped. It may take a little time to get there, but I'll give it priority.
I'd be happy to test when it's ready! However, no need to hurry: in the meantime, it is still possible (and easy) to add a dummy field to make readOGR work.
OK, thanks. SVN revision 389 committed to R-forge project rgdal, checkout from: svn checkout svn://scm.r-forge.r-project.org/svnroot/rgdal/pkg and rename pkg -> rgdal (to avoid getting multiple branches), then try R CMD check rgdal, if OK INSTALL, and try your problem. Roger
Thank you very much for you work! Mathieu.
