If you really want to return "two dataframes", then

return(list(this = dbs.this, that = dbs.that))

More likely, you want to return all the data in one dataframe.  If they 
have the same structure (columns and column names) then you want

return(rbind(dbs.this, dbs,that))

If you want something else, provide an example.

Hope this helps a little.
