Execute KNIME Model in R Server

KNIME Extensions
1

Hi,

does anyone know a general way to execute a Model which was built in KNIME on RStudio or on the RStudio Server?

As far as I know it is not possible to import/execute a Model in PMML format in R or convert it from PMML format in R based format?

I would be happy about every hint!

Greetings, Kai

Hi Kai,

It is possible to use PMML in R, see here: https://cran.r-project.org/web/packages/pmml/index.html

When using this together with KNIME, you might have to install an older version of the PMML package in R since KNIME still uses PMML 4.2, while R already uses the recently released PMML 4.3.

Cheers,

Roland

Thanks for your quick reply Roland,

I have recently read about this package, but what I understand after checking the manual is, that this package is only for exporting models which were built in R in PMML format. It does also not support a general export and provides only specific number of algorithms.

What I am looking for is a way to execute models which were built in KNIME and exportet in PMML format to be executed in R.

Does anyone maybe knows a workaround?

Kai
