I ran into a problem when trying to execute the R test script. I received the following error: Unable to communicate with the runtime for "R" script. Please check the requirements of 'R' runtime. The python script executed fine. After some research, it appears that the R Working Directory in the rlauncher.config file cannot use spaces in the path. There are several articles out there if you google the error message that can help people walk through resolving the issue.
