+## R Interpreter for Apache Zeppelin
+
+[R](https://www.r-project.org) iR is a free software environment for statistical computing and graphics.
+
+To run R code and visualize plots in Apache Zeppelin, you will need:
+
++ devtools with `install.packages("devtools", repos = "http://cran.us.r-project.org")`
++ knitr with `install.packages("knitr", repos = "http://cran.us.r-project.org")`
++ ggplot2 with `install.packages("ggplot2", repos = "http://cran.us.r-project.org")`
++ rscala: We need version 1.0.6 of Rscala, so the commands will be [1]
+
+```
+[1]
+curl https://cran.r-project.org/src/contrib/Archive/rscala/rscala_1.0.6.tar.gz -o /tmp/rscala_1.0.6.tar.gz
+R CMD INSTALL /tmp/rscala_1.0.6.tar.gz
+```
+
+Validate your installation with a simple R command:
+
+```
+print(1+1)
+```
+
+We recommend you to also install the following libraries:
+
++ glmnet
++ pROC
++ data.table
++ caret
++ sqldf
++ wordcloud
