Hi 11atzitzi,

Please find below some useful information to connect R and KNIME.

In order for KNIME to run R commands on a local installation of R, it needs to know where the R installation&nbsp;is on the machine. The default path to the R installation&nbsp;is configured from the KNIME Preferences page (“File” -\> “Preferences”-\>“KNIME”-\> “R”. Then, you would need to&nbsp;click the “Browse” button and&nbsp;select the R&nbsp;installation directory.

Please, install also the following packages:

`install.packages('Rserve')`

`install.packages('Cairo')`

Hope that helps,

Best,

Vincenzo
