To connect to Snowflake, 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 Snowflake Sys")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for Snowflake};url=https://myaccount.region.snowflakecomputing.com;user=Admin;password=test123;Database=Northwind;Warehouse=TestWarehouse;Account=Tester1;")
