I cannot get Eclipse, Statet, and R to work together. I receive an error when I launch R:

Launching the R Console was cancelled, because it seems starting the R engine failed. Please make sure that R package 'rj' (2.0 or compatible) is installed and that the R library paths are set correctly for the R environment configuration 'R test'.

I have installed Eclipse Luna (64 bit), Statet, Java 1.8.0_25 (64bit) and R 3.1.2 (64bit). I am running on windows 7 (64bit). As required I installed the packages "rj" and "rj.gd" using:

install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-2.0")

It installed fine:

I made sure that the library path is correct. I am a bit at a loss, how to proceed.

thanks for the help.

Whilst digging around in the R-environment configuration (Run -> Run configurations... -> R config -> Configure), I tried something which worked: Instead of specifying the user library link under "R_LIBS_USER", add an entry under "R_LIBS_SITE".

It works fine after that.

(I would have included visual pointers, but no rep)

  • What is the value you added for R_LIBS_USER? – Warren P Feb 02 '16 at 19:35

    @WarrenP (and likely enough for myself in a year when I get a new machine and struggle to set StatET up again): use the directory where R installs its packages, which for me currently is `.../Documents/R/win-library/3.5`. – Stephan Kolassa May 19 '18 at 15:02
  • So you can't post a screenshot because you only have 46 rep? Send me the imgur link and I'll post it. – Warren P May 21 '18 at 20:42

I set R_LIBS_USER to the /library/ folder in the R environment and it worked fine.
