SAP Predictive Analysis - Decision Trees and R

other Lumira / Visual Intelligence
#1

Hi Guys,

Sorry if this is the wrong forum section - wasn’t sure where to and this one?

If I’m understanding correctly, the new Lumira/Predictive application requires R to run certain models, yes?

I’m trying to build a simple decision tree and it just spins out (while other models will return results).

I suspect I need to download certain components into R but I’m not sure if a) Predictive is truly dependent on R for certain models and b) what R components I’m missing for the decision tree to render?

Not finding a lot of supporting documentation on Predictive either - feel free to point me in the right direction.

Thanks

Hi,

Some info for what it’s worth:
Yes, you’ll need R integration to apply decision tree models.
The R packages you 'll need to install can be found at page 4 here: http://decisionfirst.files.wordpress.com/2013/04/pablog1_installation.pdf

It’s important to follow the R steps without SAP Predictive Analysis being open.
I have a win7 64 bit (predictive analysis 1.0.11 / R version 2.15.3 / jre 1.7) , and need to follow the JVM.dll step here: http://stackoverflow.com/questions/7019912/using-the-rjava-package-on-win7-64-bit-with-r
Then I also had to re-install the rJava version as shown in the link above.
If the installation in R fails due to permissions; run R as administrator.

good luck.
