[R-SIG-Mac] RODBC

I might suggest looking into the possibility of using SQLite, which is  
cross platform and free (in fact, it's public domain rather than GNU  
etc.).

You can then set up an Excel spreadsheet to populate itself from the  
SQLite db. http://www.sqlite.org.  It's already available on the Mac -  
open a terminal window and type sqlite3, and you should enter the  
environment.  Check the website for details of how to set up the  
database connections.

Good luck -

Kent
