@MikeK glad you found a solution. For the R community nodes I found it best to combine it with RSclient and control it like this. You will have to set the port in the KNIME preferences.

```auto
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)

```

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

I collected some articles about KNIME and R. I typically would use the “official” version:
