I've managed to install StatET into eclipse, and I have a Java project called "Test" with some code in there. I'd like to be able to keep a .R file in that project folder and run it as a stand alone R script, seperate from the Java program. How can I do this? If I try to highlight some R code in a .R file and run it, it says "No session of R is active in the current workbench window."
I added a run configuration and I now have the following error in a pop up box when I try to run the R script:
Launching the R Console was cancelled, because it seems starting the R engine failed.
Please make sure that R package 'rj' (1.0.0 or compatible) is installed and that the R library paths are set correctly for the R environment configuration 'R'
You need to first start an R console from within Eclipse. Select
Run -> Run Configurations... from the menu bar. If you have not already created an R configuration, you can create a new one by right-clicking on
R Console. For more information, Longhow Lam put together a nice guide (PDF).
Regarding your new error message, make sure
rj is installed in R by running one of these commands in the command-line version of R. For the current StatET 2.0:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.0")
For the development StatET 3.0:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")
For the old StatET 0.10:
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-2.1")
