Microsoft provides the highly scalable R engine in two flavors:
- R Machine Learning Services (In-Database): This is the installation that integrates R into SQL Server. It includes a database service that runs outside the SQL Server Database Engine and provides a communication channel between the Database Engine and R runtime. You install it with SQL Server setup. The R engine includes open source R components and, in addition, a set of scalable R packages.
- Microsoft R Server: This is a standalone R server with the same open and scalable packages that run on multiple platforms.
For development, you prepare a client installation. You can download Microsoft R Client from http://aka.ms/rclient/download ...
