Dear all,
I'm trying to save some shapes to a postGIS table. I can do it by:
shape <- readShapePoly(...)
writeOGR(shape, dsn="PG:dbname=gis user=gis password=...", layer='onetable',
driver="PostgreSQL", layer_options="overwrite=yes")
It empties the "onetable" table. Then, how could I do if I want to add other
shape to this table without overwritting it?
I've searched for the params of "layer_options", but I didn't find nothing.
Thank you!
