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!
Germán Sánchez
