Call the function stats.get_data() with the parameters string and the name of the output file (without the extension). Its very easy to export data stored in nc_sweetpotato_data or sampson_sweetpotato_data as a comma-separated variable file (.CSV) in R. To do this, you can use the write_csv( ) function. Filter lists are refreshed based upon user choice allowing the user to fine-tune the search.
