I tried to install R extension through Marketplace, however, that didn't work because of proxy setting.

Then I read something about downloading the jar file from here: http://sourceforge.net/projects/rapidminer/files/2.%20Extensions/
and copying into the 'plugin' folder.

My question is that there are three additional files listed for R extension:
src.zip, javadoc,zip and installer.exe
Do we need all these four files? Or one jar file is enough?

Thanks.

Hi,

with RapidMiner Studio 6.4, we have deprecated the old R extension and released the "R Scripting" extension. You can simply download that from our marketplace: https://marketplace.rapidminer.com/UpdateServer/faces/product_details.xhtml?productId=rmx_r_scripting
Then place it in your USER_HOME/.RapidMiner/extensions folder and start Studio again.

Cheers,
Marco

Thanks for your reply.

I downloaded the rmx_r_scripting-ANY-6.4.0. However, I couldn't find the 'extensions' folder under  USER_HOME/.RapidMiner. Do I need to create one?

I have another question:
Do you have a link to Python extension?

Hi,

yes, you have to create it in your case.
Python extension: https://marketplace.rapidminer.com/UpdateServer/faces/product_details.xhtml?productId=rmx_python_scripting

By the way, in the top right corner of the marketplace is a search field Smiley

Thanks so much for your prompt response.

I put the 'rmx_r_scripting-ANY-6.4.0' file in the extensions folder. However, still couldn't find 'Execute R' in Rapidminer after re-start.

Do I need to do anything to build the connection between R and Rapidminer?

The documentation for 'Execute R' specifies that
'Before using this operator you need to specify the path to your R installation under Tools -> Preferences -> R Scripting. Your R installation has to include the 'data.table' package.'.

However, there is no 'R-scripting' tab under Tools -> Preferences in my RapidMiner

Hi,

Sorry, I may have confused the folder where to put the extension. It's possible that the folder I mentioned will only be used from 6.5 onward, I'm not entirely sure at the moment. Can you instead put the extension into your Studio/lib/extensions folder?
You should then find the operator in the "operators" view. You can then add it to your process and follow the instructions on how to set up R.
The exact same process can be used for the Python extension as well.

Regards,
Marco
