To use the community R source node you will have to start the RServe from R itself. 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
