The R snippet in KNIME

Hi Felix,

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?

 

Kind regards,
Di Zi


 

Forget to say thanks again for your effort :)

Hi Di Zi

to see if the Rserver is running you can check in the Task Manager in Windows or the Activity Monitor on a Mac, if you find a process called "Rserve-bin.so". If it is not there triy to launch it from the R console. Detailed instruction about how to install and launch Rserve can be found here.
