Connecting
To connect to Informix, you can use either a DSN or an ODBC connection string. Both of these methods use the odbcConnect function.
Connect to a DSN
To connect using a DSN:
cnx <- odbcConnect("CData Informix Sys")
Provide a Driver Connection String
To connect using an ODBC connection string:
cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for Informix};Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test")
