R dataframes printing as plain text

[Mark Miller <ma...@gmail.com>]

I'm new to Zeppelin, Spark and Scala

According to https://zeppelin.apache.org/docs/0.6.2/interpreter/r.html,
"If you return a data.frame, Zeppelin will attempt to display it using
Zeppelin's built-in visualizations"

But I am just getting a plain text dump from "mtcars"

What am I doing wrong?

thanks,
Mark

I installed zeppelin-0.7.1-bin-all.tgz on an Ubuntu 16 system with openjdk
version "1.8.0_121"

I installed spark-2.1.1-bin-hadoop2.7.tgz in /usr/local/share/spark

i.e., I can run
$ /usr/local/share/spark/spark-2.1.1-bin-hadoop2.7/bin/run-example SparkPi
10

I edited zeppelin-env.sh to say:
export SPARK_HOME=/usr/local/share/spark/spark-2.1.1-bin-hadoop2.7

I did
$ cp zeppelin-site.xml.template zeppelin-site.xml

and
$ ./bin/zeppelin-daemon.sh restart

I don't think it support R's dataframe. Not sure why the document says
it works, may it works before.
