I recently upgraded from KNIME 2.11 to KNIME 3.3 on Windows 7 using the self-extracting zip installation.
I have been using the R statistics integration nodes in 2.11 but now I cannot initialize those nodes.
At the beginning, KNIME console threw the message related to R library "Rserve" was not installed.
But after the installation, I still cannot initialize the nodes.
I wonder if anything else I can check.
Instead of using my original R installation, I restored to the default using the copy provided by KNIME.
And it worked.
Still do not understand why R nodes cannot be initialized when "path to R Home" is set to my original R installation.
