I have installed Apache Zeppelin 0.6.1 and tried R interpreter. But I've had issue about built-in visualizations.
(Debian Jessie 8.2)
There is sentece in Apache Zeppelin documentation https://zeppelin.apache.org/docs/0.6.1/interpreter/r.html:
*If you return a data.frame, Zeppelin will attempt to display it using
Zeppelin's built-in visualizations.*
I dont see options (table, line chart,bar chart etc..).
Output is simple text only.
