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

[Janko Thyson]

Thanks for the quick reply. I was following your hint with "rJava", but I'm still a little lost.

I maybe should have added that the console terminating happens when launching it as "Rterm", it works fine when running it as "RJ". However, I would like to use "Rterm". Here is what I did so far:

First of, I'm still confused about Ubuntu's "sudo" way of doing things. 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". 

Then, launching R as "RJ" and trying to execute an "install.packages()", Ubuntu prompted me for the specification of a valid library directory and offered to create "/home/<ME>/i486-pc-linux-gnu-library/2.10". 

So ".libPaths()" would give me:
    R> .libPaths()
    [1] "/home/<ME>/i486-pc-linux-gnu-library/2.10" "/usr/lib/R/site-library"       
    [3] "/usr/lib/R/library"           
    R>

I then tried to "re-install" the package "rJava" by "install.packages()" which got me the following output:

So I ran "sudo R CMD javareconf", but still get the same error.

Any hints from here on?

Thanks a lot!

It so happens that I help a colleague recently to triage this.  The problem
there was that a recent rJava was needed + and installed -- and on Ubuntu and
Debian this goes into 

       /usr/local/lib/R/site-library/

and StatET -- as shipped -- does not look there.  I don't use Eclipse so I
don't recall where to set this, but in essence you need to make sure that
StatET looks where R puts things. And that tends to be

    R> .libPaths()
    [1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"       
    [3] "/usr/lib/R/library"

CCing Tobias just in case.
