It’s been a busy short week, with the Thanksgiving holiday, putting up Christmas decorations, and the time consuming task I like to call my job. But I did start to play with the rlauncher config file. Not much, just in setting the workspace R will be using.

This is the line that defines the default workspace

WORKING_DIRECTORY=C:\PROGRA~1\MICROS~2\MSSQL1~1.MSS\MSSQL\EXTENS~1 

Books Online has a note that warns not to change the value. But hey, this is just a CTP, right? Why not test that out? So I changed the value to a new folder, C:\SQL2016\RWorkspace. Afterwards,checking the working directory didn’t give me the result I was expecting.

Not only that, I got a different result each time I ran the script. Each time a new sub-directory was created.

I reset the value of the working directory back to the default. And I’ll leave it as is. If I want to change the working directory, maybe to store functions I can source out later, I’ll change it in my script.

I’m not done with the rlauncher config yet, I’ll have more later.
