David Smith describes sqlrutils, an R function to generate SQL Server R Services stored procedures:
If you’ve created an R function (say, a routine to clean up missing values in a data set, or a function to make forecasts using a machine learning model), and you want to make it easy for DBAs to use it, it’s now possible to publish R functions as a SQL Server 2016 stored procedure. The sqlrutils package provides tools to convert an existing R function to a stored procedure which can then be executed by anyone with authenticated access to the database — even if they don’t know any R.
To use an R function as a stored procedure, you’ll need SQL Server 2016 with R Services installed. You’ll also need to use the sqlrutils package to publish the function as a stored procedure: it’s included with both Microsoft R Client (available free) and Microsoft R Server (included with SQL Server 2016), version 9.0 or later.
Compare this against R Tools for Visual Studio, with which you can generate stored procedures from the IDE.
