After installing and configuring FreeTDS and unixODBC and confirming they are working correctly, I am trying to configure RODBC. However, I am getting the following results when attempting to view the ODBC data sources in the R console.
> odbcDataSources()
named character(0)
If I attempt to use the FreeTDS driver I get the following results.
>odbcDriverConnect("driver={FreeTDS};server=xx.xx.xx.xx;port=1433;database=XXXX_Analysis;trusted_connection=true;UID=********;PWD=********") :
[RODBC] ERROR: state IM003, code 0, message [iODBC][Driver Manager]Specified driver could not be loaded
Based on the error, it looks like RODBC is trying to use iODBC instead of unixODBC. I am not sure how to configure RODBC to use unixODBC.
