Have you seen our webinar on YouTube about the R Integration in KNIME?

https://www.youtube.com/playlist?list=PLz3mQ6OlTI0a19_DlmbeRvjz-pTg-AWW4

Once small difference between the nodes in that video and the current releaes of KNIME is that the R nodes shown have been moved to a top level group in the node repository.

Hi Jing, 

First, make sure you are using the latest version of KNIME (2.10).   From the R version that you would like to use with KNIME, try typing "R.home()".  This will give you a path to that R installation's home directory. You will also need to install the R packages "rJava" in this instance of R.  You can then point KNIME to this R installation from the R section of the KNIME Preferences.  You may need to restart KNIME, but after that you should be good to go. 

Regards,

Aaron
