Hi Ashish, Thank you for providing the r interpreter integration in the below repository and all your help with configuring it:
https://github.com/Peaceful-learner/incubator-zeppelin/tree/rinterpreter <https://github.com/Peaceful-learner/incubator-zeppelin/tree/rinterpreter> The integration of graphics output and SparkR works really well! In case others find it helpful, setting it up required the following steps (for me at least, on OS X) which Ashish kindly guided me through: Install the following R packages: evaluate (required to compile the code in the repository) devtools ggtools2 googleVis knitr base64enc htmltools and repr,rCharts and devtools using: library(devtools) devtools::install_github("IRkernel/repr”) devtools::install_github('apache/spark@v1.4.1', subdir='R/pkg’) devtools::install_github('rCharts', 'ramnathv') clone the repository and switch to the rinterpreter branch. build using: mvn clean package -DskipTests and finally add org.apache.zeppelin.rinterpreter.RRepl,org.apache.zeppelin.rinterpreter.KnitR to the list of interpreters in the conf/zeppelin-site.xml file and start zeppelin - no need to create or copy any jars into interpreter/r. the interpreter is then available as %spark.r.
