Hi, I've just pushed to my repo my version of the RInterpreter: https://github.com/leonardofoderaro/incubator-zeppelin/tree/r-interpreter/R
it's a work in progress, I'm still working on the proper output format (e.g. if the result of your expression is a vector actually you get only the first element) and the plot support. it uses a Map<String, RConnection> to provide session isolation at notebook level (the key of the Map is the nodebook id) I don't know if it's the right way to implement it (to avoid multiple notebooks sharing and overwriting the same R variables), feel free to give it a try and let me know if you think it's pointing in the right direction. thanks, Leonardo On Mon, Sep 28, 2015 at 8:24 AM, Ashish Dalal <dalalstree...@gmail.com> wrote: > Hi All, > Also, I tried the zeppelin-R repo provided by the datalayer.io folks but > could not get it to working.
