Hi,
I'm getting "ERROR_FROM_R" when I try to run any R algorithm (Boosting, Random Forest, CNR) on Expert Analytics. I've managed to successfully run the Auto Classification algorithm. I've installed the required packages (including rJDBC, RODBC and rJava), and the R configuration points to the folder that R 3.3.0 was installed in.. What does this mean/what should I do? Error log is below. Using SAP Predictive Analytics 3.1.1
Thanks in advance for any help.
