If you use the R::setup() you don't need this method. This method is meant
for multiple database setups. This method selects the database identified by the
database ID ($key). Use addDatabase() to add a new database, which in turn
can be selected using selectDatabase(). If you use R::setup(), the resulting
database will be stored under key 'default', to switch (back) to this database
use R::selectDatabase( 'default' ). This method returns TRUE if the database has been
switched and FALSE otherwise (for instance if you already using the specified database).
