JavaR

JavaR is a library that enables the integration between Java and R languages through Rserve (https://www.rforge.net/Rserve/).

Prerequisites

• R programming language (https://www.r-project.org/about.html).
• X11 libraries (Only on OS X systems). If not istalled, you can download it from: https://www.xquartz.org/.

Configuration (Unix platforms)

The following steps are required in order to use the JavaR library:

• Rserve installation

1. Start R: type "R" on terminal.
2. Install Rserve: type "install.packages("Rserve")" on R console.

• Starting up Rserve (Optional, JavaR can start Rserve automatically)

1. Start R: type "R" on terminal.
2. Declare the usage of Rserve: type "library('Rserve')" on R console.
3. Start Rserve daemon: type "Rserve()" on R console.

• Enabling automatic start of Rserve (Optional)

1. Start R: type "R" on console.
2. Detect current Rserve library location: type "system.file("libs", "Rserve", package="Rserve")" on R console. Copy the Rserve location (e.g., /home/lfrivera/R/x86_64-pc-linux-gnu-library/3.2/Rserve/libs/Rserve)
3. Create a symbolic link of Rserve in the R bin folder: type the following command on terminal: "ln -s CURRENT_RSERVE_LIBRARY_LOCATION /usr/lib/R/bin/Rserve" (e.g., ln -s /home/lfrivera/R/x86_64-pc-linux-gnu-library/3.2/Rserve/libs/Rserve /usr/lib/R/bin/Rserve).
