@thentangler I do not have a consitant guide how to obtain the batch log. You should check out some threads in the forum about that.

Currently I would assume the problem might be with the R lubridate library. What [version of R](https://kni.me/w/annQfxz-Mrtn2BNm) are you using?

You could try and use the [community R nodes](https://nodepit.com/category/community/r), but that would mean you have to have R with Rserve running when knime is being started. Never tried that with a batch system.

Like this (you will have to have Rserve and RSclient installed): library(Rserve) library(RSclient) Rserve(port = 6311, debug = FALSE, args = “–vanilla”) # start the RServe(er) rsc \<- RSconnect(port = 6311) # shutdown the server after you used it RSshutdown(rsc) And you will have to set the preferences
