[R] how to disable RODBC log file

[Tamas K Papp]

I am using RODBC with Postgresql.  I have disabled the log file in
~/.odbc.ini, but nevertheless I still get a logfile in /tmp, which can
grow to gigabytes, so I would like to disable it.

It appears that the logfile is generated by R:

% lsof | grep /tmp/psqlodbc_tpapp7482.log
R         7482       tpapp    3w      REG        3,5     3127    1668135 /tmp/psqlodbc_tpapp7482.log

Could somebody please tell me how to disable this logfile?  I have
searched the list and help, but found nothing about this.

Thanks,

Tamas
