To connect to Amazon S3, 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 AmazonS3 Sys")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for Amazon S3};AWSAccessKey=a123;AWSSecretKey=s123;")
