Tomaz Kastrun shows how to include R scripts (and visuals) in SQL Server Reporting Services:
Using the privileges of R language to enrich your data, your statistical analysis or visualization is a simple task to get more out of your reports.
The best practice to embed R code into SSRS report is to create stored procedure and output the results to report. To demonstrate this, we will create two reports; one that will take two input parameters and the second one to demonstrate the usage of R visualization.
It’s nice to be able to use R to create nice visuals and then import them in your SSRS report, and Tomaz shows how.
