Hi Rajendra,
if you want to use the Scripting Integration nodes and Rserve, then follow the URL in the help of the node descrition:
https://github.com/knime-mpicbg/knime-scripting/wiki/R-server-for-knime
(I agree, this documentation needs some update/clarification... it is on our to do list...)
In brief:
on your windows machine:
- install KNIME, Scripting Integration nodes and R/R-Rstudio
- install and start Rserve (in R: install.packages("Rserve"); library(Rserve); Rserve(args='--vanilla');)
- make sure that Rserve.exe is running in the task manager
- first, try your local Rserver: Preferences -> R-Scripting -> The host... type in "localhost". The port is 6311.
- drag and drop R snippet from Scripting Integration, connect to some input data and execute (sends data to Rserver and gets it back) -> green node? great! you have installed a local Rserver!
- second, install R and Rserve and start Rserve on your linux machine (see above)
- set host in preferences now to the IP address of your linux machine and try to execute the snippet again
- you might need to follow the instructions on the website mentioned above to get it running!?
Good luck!
Martin
