Arguments

`conn`	A duckdb_connection object as returned by `DBI::dbConnect()`
`name`	The table name, passed on to `dbQuoteIdentifier()`. Options are: a character string with the unquoted DBMS table name, e.g. `"table_name"`, a call to `Id()` with components to the fully qualified table name, e.g. `Id(schema = "my_schema", table = "table_name")` a call to `SQL()` with the quoted and fully qualified table name given verbatim, e.g. `SQL('"my_schema"."table_name"')`
`value`	A data.frame (or coercible to data.frame).
`...`	Other parameters passed on to methods.
`row.names`	Whether the row.names of the data.frame should be preserved
`dbObj`	An object inheriting from class duckdb_connection.
`obj`	An R object whose SQL type we want to determine.
`statement`	a character string containing SQL.
`params`	For `dbBind()`, a list of values, named or unnamed, or a data frame, with one element/column per query parameter. For `dbBindArrow()`, values as a nanoarrow stream, with one column per query parameter.
`arrow`	Whether the query should be returned as an Arrow Table
`overwrite`	If a table with the given name already exists, should it be overwritten?
`append`	If a table with the given name already exists, just try to append the passed data to it
`field.types`	Override the auto-generated SQL types
`temporary`	Should the created table be temporary?
`object`	Any R object
