Hi, Leonardo and Stefan, I have forked the following https://github.com/elbamos/incubator-zeppelin/tree/rinterpreter/ and after resolving some build issues , I was able to get R running successfully on my local machine. I would be committing my code to my local repo in short while from now. You can give it a try. Also, Leonardo, I think for rendering R graphics inline on the zeppelin, you got to install the repr package in R, now repr also is not a standard package in R but you can it via the following command. devtools::install_github("IRkernel/repr")
