rgdal writeOGR - clipping variable names

On Mon, Jul 7, 2014 at 4:44 AM, Barry Rowlingson

At the moment with rgdal I can't figure out how to add several layers
to a single Spatialite file or overwrite a single existing layer but I
suspect I'm just missing an option or two. I can just delete the
.sqlite file and recreate it, but that's an annoyance... Oh well,
there has to be one doesn't there?

Interesting. This can be done at the terminal with ogr2ogr, but
requires the -update switch. ogr2ogr requires the -update switch to
add a layer to a SpatiaLite file, but not to PostGIS. Hence, writeOGR
can add layers to PostGIS but not to SpatiaLite.

I don't think there's any way to pass the -update switch via writeOGR,
as it is not a dataset creation option or layer creation option.

Best,
