Exit code 4 when using R node

@thentangler these things come to my mind.

You should check if you can do these transformations in knime so you would not need to use R.

Then you could try and use R thru Miniconda and Conda Environment Propagation.

Then you might want to check a complete log file to see what is going on.

Also there are hints that this might be a thing about the lubridate package specifically.
