Details

The function calls gpsbabel via the system. The gpsbabel program must be present and on the user's PATH for the function to work see http://www.gpsbabel.org. A .gpx suffix is added if not included in the filename. The gpx file can then be read e.g. using readOGR to a sp spatial object. Ex: readOGR("filename.gpx", "waypoints", drop_unsupported_fields=TRUE), or uploaded to a GPS
