I was playing with the new "R" scripting in SQL Server 2016 CTP 30.
Finally got it working, thanks to this site.
I've had a problem that I'm sure others will run into as well.
All of a sudden the "R" scripts no longer worked, they returned this error:
Msg 39011, Level 16, State 1, Line 1
SQL Server was unable to communicate with the LaunchPad service. Please verify the configuration of the service.
