dbWriteTable() of PostGIS enabled database

[Ty Frazier]

I'm trying to import a spatial database (PostGIS) to R using the RpostgreSQL package.  When I use the command

enum_areas <-dbReadTable(con,"enum_areas")

 

I get the following error.

Warning message:

In postgresqlExecStatement(conn, statement, ...) :

  RS-DBI driver warning: (unrecognized PostgreSQL field type geometry (id:31716) in column 6)

Any pointers on how to read/write a spatial database between R/postgresql and preserve the geometry without going through an extra step (such as using a merge and/or join statement).

Thanks,

Ty
