Manage huge database

Hello, Yihui

You can treat it as a database and use ODBC to fetch data from the CSV
file using SQL. See the package RODBC for details about database
connections. (I have dealt with similar problems before with RODBC)

Thanks for your tip, I have used RODBC before to read data from MSAccess and
MSExcel files, but never I imagined it could work for non-database files
such as csv.

I will check the RODBC documentation.

Best Regards,
Jose Lozano
