batch mode only: Cannot determine major version of R

Hi everyone,

when I run an R node in batch mode, Knime tells me it cannot determine the major version of R. The same workflow runs fine in the GUI. The R preferences page shows no errors, either.

Any hints what might go wrong here?

Versions are Knime 3.2.1 (console says 3.2.2) and R 3.2.2.

Best,

Lorenz
