This is the initial PR for an R Interpreter for Zeppelin. There's still some work to be done (e.g., tests), but its useable, it brings to Zeppelin features from R like its library of statistics and machine learning packages, as well as advanced interactive visualizations. So I'd like to open it up for others to comment and/or become involved. Summary: - There are two interpreters, one emulates a REPL, the other uses knitr to weave markdown and formatted R output. The two interpreters share a single execution environment. - Visualisations: Besides R's own graphics, this also supports interactive visualizations with googleVis and rCharts. I am working on htmlwidgets (almost done) with the author of that package, and a next-step project is to get Shiny/ggvis working. Sometimes, a visualization won't load until the page is reloaded. I'm not sure why this is. - Licensing: To talk to R, this integrates code forked from rScala. rScala was released with a BSD-license option, and the author's permission was obtained. - Spark: Getting R to share a single spark context with the Spark interpreter group is going to be a project. For right now, the R interpreters live in their own "r" interpreter group, and new spark contexts are created on startup. - Zeppelin Context: Not yet integrated, in significant part because there's no ZeppelinContext to talk to until it lives in the Spark interpreter group. - Documentation: A notebook is included that demonstrates what the interpreter does and how to use it. - Tests: Working on it... P.S.: This is my first PR on a project of this size; let me know what I messed up and I'll try to fix it ASAP. Author: Amos Elb <amos.elberg@me.com> Author: Amos B. Elberg <amos.elberg@me.com> Closes #208 from elbamos/rinterpreter and squashes the following commits:ffc1a25[Amos Elb] Fix rat issuea08ec5b[Amos B. Elberg] R Interpreter
