I wanted a “lightweight” version of Eclipse to run R from Ubuntu. (I installed eclipse-pde using apt-get. It worked fine.) Once it was running, I installed StatEt via the “Install new software” feature from
http://download.walware.de/eclipse-3.5. While it was downloading, I opened up an R console and ran
install.packages("rJava"). When the installation of both StatEt and rJava finished I restarted Eclipse. This is when things stopped working and I couldn’t really find any step-by step directions on how to proceed. Here is what I did:
- Run -> Run Configurations
- Click on R-Console in the left pane. This will create a new run configuration. Change the name to “R 2.10″
- Click on the “R_Config” tab. Choose “Selected Configuration:” and then hit the “Configure…” button.
- Click “Add”. Change “Location (R_Home):” to “/usr/lib/R” and click “Detect Default Properties/Settings” Click “Ok” until you are back to the “Run Configurations” window
- This is the important step. Without it you will get
Launching the R Console was cancelled, because it seems starting the Java process/R engine failed. Please make sure that R package 'rJava' with JRI is installed and look into the Troubleshooting section on the homepage.
Click on the JRE tab. In the “VM Arguments” box add
is your username. (You are providing the path to rJava, for some reason, even though Eclipse will detect it during the setup in the “R_Config” step, it doesn’t seem to share that information with the JRE.)
- Click Run. It should work.
