Exporting R data.frame/tbl to Google BigQuery table
It looks like bigrquery package does the job with insert_upload_job(). In the package documentation, it says this function 
> is only suitable for relatively small datasets
but it doesn't specify any size limits. For me, it's been working for tens of thousands of rows.
I know it's possible to import Google BigQuery tables to R through bigrquery library. But is it possible to export tables/data frames created in R to Google BigQuery as new tables? 
Basically, is there an R equivalent of Python's temptable.insert_data(df) or df.to_sql() ? 
thanks for your help,
