I am experiencing a strange problem with R Snippets in KNIME 3.5.3 on a macOS (high sierra 10.13.4 (17E202)) system since switching to the newest R version 3.5. It seems to be there with every R Snippet I use that generates an output table, the system is not able to get back knime.out parameters and throws strange error messages. The first part using R does work so there does not seem to be a general R problem.
Well yes I tried to reinstall R, I made sure I have RServe and Cairo up and running and I also tried starting RServe separately and I tried to use every variant of R Scripting there is. And yes I also installed XQuartz …
It looks as if the KNIME R Snippets are expecting some meta variables or something that might not be there anymore with R 3.5.
I am wondering if other macOS users also have this problem or if I have to look further into my configuration.
