Thank you very much for replying! I have already linked to the new templates following the R-Server installation instructions on wiki. But somehow it still gives me the error "Execute failed: eval failed, request status: error code: 127". So I download the template to my local folder, and try to debug it. I find it has difficulties to recognize variable rOut and kIn. I don't know if this is the reason and what cause it?
I tried also other people's templates, same error shows up. Maybe it is because R-Server is not connected? How can I know I install the R-server correclty?
