R-Learner error: R-inDataTempFile cannot be found

[sl]

Hi

Just installed knime 2.9.0 and tried R-Learner with R-3.1.0

I get the error which indicates that a temporal file *.r.Rout in a c:\Tmp folder wasn't found. 

I see that some empty *.R files are being created in my temporal folder each time I execute the R-Learner but no r.Rout

Any ideas?

Thanks

Sl

Do you have a small workflow which demonstrates the problem, I am happy to look into the problem?
