writeOGR to GPX file: empty table

Sorry about not having read the doc, I'm probably too used to import shape files with readOGR() and did not realize that GPX files would have different options. test <- readOGR(dsn="/media/TRANSCEND/MONTSENY2008/MONTSENY_GEODATA/FloraExotica2009/AilantMSY09R.gpx",layer="waypoints") works fine and the table is correct. I think that dataset_options="GPX_USE_EXTENSIONS=YES" at writing did the job. So no problem at all with writing/reading GPX files in R through rgdal I would add a line to the help page reminding the user that coordinates must be geographic in GPX files (thus the user must eventually unproject before writeOGR() ).
OK, will do. Roger
Thanks! Agus
