how to call .R

Anonymous — Mon, 10 Jun 2013 15:30:35 GMT

Hi - I have downloaded and installed R from revolution analytics on my machine. How do I call the .R scripts from Talend so that I can run these scripts on a scheduled basis? I have searched the forum but didn't find any relevant posts. Can anyone give me some pointers? Do I need to wrap .R in a java script, php, or shell script?
Thanks,

I have no clue about "R". Could you please provide a sample of explanation of the structure.

Hi CW,
I have never tried calling an R function from Talend. That said, create a java wrapper that can be called by Talend and will call your R function. I believe you want to use RCaller when making the java to R call.
Let let me know how that works.
