Scalable and distributive computational environments

The RevoScaleR package has the following functions available, which will be covered in detail throughout the chapter.

To get a list of all the ScaleR functions, the following T-SQL can be used:

EXEC sp_execute_external_script
      @language = N'R'
      ,@script = N'require(RevoScaleR)
                        OutputDataSet <- data.frame(ls("package:RevoScaleR"))'
WITH RESULT SETS
      (( Functions NVARCHAR(200)))  

You get a table in SSMS with all the relevant rx functions that can be used with the RevoScaleR package.

Based on the list of these functions, a simpler and better overview of the functions can be prepared:
