Dear Karim,

Ok, I had downloaded the plain "biocep.jar". I have now replaced it by
"RWorkbench_NO_R.zip" (as I already have R 2.8.1 on my system).

This made the trick and no longer it tries to install the packages. BTW, I
think the packages could not be installed because an internet connection is
only available on my system using the command-line parameter --internet2 when
invoking R. Is there a way to parametrize the way a local R server is launched?
In the same vein, is there a way to load an .Rprofile file on startup?
But then, a java exception was thrown with a message telling that it could not
locate the native JRI library. Adding the path to it on the command line didn't
solve it:
java -Djava.library.path=C:\Progra~1\R\R-2.8.1\library\rJava\jri
-Duse.default.libs=true -jar biocep.jar
In case someone is in the same situation, I've solved both problems by manually
installing from within R the required packages (rJava, JavaGD, TypeInfo, Cairo
and iplots) on directory "<RBenchmarkPath>\library\R-version-2.8.1". Now
everything works!
Many thanks for your answer and help.
Best,
Enrique
