+## R Interpreter
+
+This is a the Apache (incubating) Zeppelin project, with the addition of support for the R programming language and R-spark integration.
+
+### Requirements
+
+Additional requirements for the R interpreter are:
+
+ * R 3.1 or later (earlier versions may work, but have not been tested)
+ * The `evaluate` R package. 
+
+For full R support, you will also need the following R packages:
+
+ * `knitr` 
+ * `repr` -- available with `devtools::install_github("IRkernel/repr")`
+ * `htmltools` -- required for some interactive plotting
+ * `base64enc` -- required to view R base plots
+
+### Configuration 
+
+To run Zeppelin with the R Interpreter, the SPARK_HOME environment variable must be set. The best way to do this is by editing `conf/zeppelin-env.sh`. 
+
+If it is not set, the R Interpreter will not be able to interface with Spark. 
+
+You should also copy `conf/zeppelin-site.xml.template` to `conf/zeppelin-site.xml`.  That will ensure that Zeppelin sees the R Interpreter the first time it starts up. 
+
+### Using the R Interpreter
+
+By default, the R Interpreter appears as two Zeppelin Interpreters, `%r` and `%knitr`. 
+
+`%r` will behave like an ordinary REPL.  You can execute commands as in the CLI.   
+
+[![2+2](screenshots/repl2plus2.png)](screenshots/repl2plus2.png)
+
+R base plotting is fully supported
+
+[![replhist](screenshots/replhist.png)](screenshots/replhist.png)
+
+If you return a data.frame, Zeppelin will attempt to display it using Zeppelin's built-in visualizations. 
+
+[![replhist](screenshots/replhead.png)](screenshots/replhead.png)
+
+`%knitr` interfaces directly against `knitr`, with chunk options on the first line:
+
+[![knitgeo](screenshots/knitgeo.png)](screenshots/knitgeo.png)
+[![knitstock](screenshots/knitstock.png)](screenshots/knitstock.png)
+[![knitmotion](screenshots/knitmotion.png)](screenshots/knitmotion.png)
+
+The two interpreters share the same environment.  If you define a variable from `%r`, it will be within-scope if you then make a call using `knitr`.
+
+### Using SparkR & Moving Between Languages
+
+If `SPARK_HOME` is set, the `SparkR` package will be loaded automatically:
+
+[![sparkrfaithful](screenshots/sparkrfaithful.png)](screenshots/sparkrfaithful.png)
+
+The Spark Context and SQL Context are created and injected into the local environment automatically as `sc` and `sql`.
+
+The same context are shared with the `%spark`, `%sql` and `%pyspark` interpreters:
+
+[![backtoscala](screenshots/backtoscala.png)](screenshots/backtoscala.png)
+
+You can also make an ordinary R variable accessible in scala and Python:
+
+[![varr1](screenshots/varr1.png)](screenshots/varr1.png)
+
+And vice versa:
+
+[![varscala](screenshots/varscala.png)](screenshots/varscala.png)
+[![varr2](screenshots/varr2.png)](screenshots/varr2.png)
+
+### Caveats & Troubleshooting
+
+* Almost all issues with the R interpreter turned out to be caused by an incorrectly set `SPARK_HOME`.  The R interpreter must load a version of the `SparkR` package that matches the running version of Spark, and it does this by searching `SPARK_HOME`. If Zeppelin isn't configured to interface with Spark in `SPARK_HOME`, the R interpreter will not be able to connect to Spark. 
+
+* The `knitr` environment is persistent. If you run a chunk from Zeppelin that changes a variable, then run the same chunk again, the variable has already been changed.  Use immutable variables. 
+
+* (Note that `%spark.r` and `$r` are two different ways of calling the same interpreter, as are `%spark.knitr` and `%knitr`. By default, Zeppelin puts the R interpreters in the `%spark.` Interpreter Group.
+
+* Using the `%r` interpreter, if you return a data.frame, HTML, or an image, it will dominate the result. So if you execute three commands, and one is `hist()`, all you will see is the histogram, not the results of the other commands. This is a Zeppelin limitation.
+
+* If you return a data.frame (for instance, from calling `head()`) from the `%spark.r` interpreter, it will be parsed by Zeppelin's built-in data visualization system.  
+
+* Why `knitr` Instead of `rmarkdown`?  Why no `htmlwidgets`?  In order to support `htmlwidgets`, which has indirect dependencies, `rmarkdown` uses `pandoc`, which requires writing to and reading from disc.  This makes it many times slower than `knitr`, which can operate entirely in RAM. 
+
+* Why no `ggvis` or `shiny`?  Supporting `shiny` would require integrating a reverse-proxy into Zeppelin, which is a task. 
+
+* Max OS X & case-insensitive filesystem.  If you try to install on a case-insensitive filesystem, which is the Mac OS X default, maven can unintentionally delete the install directory because `r` and `R` become the same subdirectory. 
+
+* Error `unable to start device X11` with the repl interpreter.  Check your shell login scripts to see if they are adjusting the `DISPLAY` environment variable.  This is common on some operating systems as a workaround for ssh issues, but can interfere with R plotting. 
+
+* akka Library Version or `TTransport` errors.  This can happen if you try to run Zeppelin with a SPARK_HOME that has a version of Spark other than the one specified with `-Pspark-1.x` when Zeppelin was compiled.
