[R] dbWriteTable with row.names=(TRUE | FALSE)

[Hansruedi Baetschmann]

Hello

Saving a dataframe with dbWriteTable to a relational database with the 
parameter row.names set to FALSE works fine, doing so the parameter set 
to TRUE gives an error message "/Fehler in field.types$row.names : $ 
operator is invalid for atomic vectors/"  (see the protocol below).

I work with R Ver.2.7.1

What am I doing wrong ?

Thanks
