[R] Ubunut + Eclipse + StatET: Console terminates upon error

[Tobias Verbeke]

Hi Janko,

I'm not an rJava install expert (on all but my own system
I often end up setting the appropriate environment variables
related to Java manually before launching the R CMD
INSTALL for the package), but with respect to the choice
Rterm vs. RJ Console, I would strongly advise to use the
RJ Console. It allows for a much richer IDE experience,
particularly through the Object Browser and Content Assist
(Content Assist corresponds in non-Eclipse lingo to command
completion and hover pop-ups in the editors and R Console).

Best,
Tobias

Not knowing how to authorize me as "root" when installing packages from a R-script, I can't write on "/usr/local/lib/R/site-library" or "/usr/lib/R/site-library". So I turned to Synaptics, found and installed the CRAN package "rJava" that enables me to run the R console with Launch Type "RJ" within Eclipse. "rJava" went into "/usr/lib".
