To connect to Microsoft SQL Server Analysis Services, 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 SSAS Sys")

Provide a Driver Connection String

To connect using an ODBC connection string:

cnx <- odbcDriverConnect(connection = "DRIVER={CData ODBC Driver for Microsoft SQL Server Analysis Services};User=myuseraccount;Password=mypassword;URL=http://localhost/OLAP/msmdpump.dll;")
