Arguments

`object`	Any R object
`drv`	an object that inherits from DBIDriver, or an existing DBIConnection object (in order to clone an existing connection).
`project`	The project name, a string
`dataset`	The name of the dataset to create, a string
`billing`	project ID to use for billing
`page_size`	Number of items per page.
`quiet`	if `FALSE`, prints informative status messages.
`use_legacy_sql`	(optional) set to `FALSE` to enable BigQuery's standard SQL.
`...`	authentication arguments needed by the DBMS instance; these typically include `user`, `password`, `host`, `port`, `dbname`, etc. For details see the appropriate `DBIDriver`.
`dbObj`	An object inheriting from DBIObject, i.e. DBIDriver, DBIConnection, or a DBIResult
`obj`	An R object whose SQL type we want to determine.
`conn`	A DBIConnection object, as returned by `dbConnect()`.
`statement`	a character string containing SQL.
`x`	A character vector to quote as string.
`name`	A character string specifying the unquoted DBMS table name, or the result of a call to `dbQuoteIdentifier()`.
`value`	a data.frame (or coercible to data.frame).
`overwrite`	a logical specifying whether to overwrite an existing table or not. Its default is `FALSE`.
`append`	a logical specifying whether to append to an existing table in the DBMS. Its default is `FALSE`.
`row.names`	A logical specifying whether the `row.names` should be output to the output DBMS table; if `TRUE`, an extra field whose name will be whatever the R identifier `"row.names"` maps to the DBMS (see `DBI::make.db.names()`). If `NA` will add rows names if they are characters, otherwise will ignore.
`res`	An object inheriting from DBIResult.
`n`	maximum number of records to retrieve per fetch. Use `n = -1` or `n = Inf` to retrieve all pending records. Some implementations may recognize other special values.
`params`	A list of bindings, named or unnamed.
