I am new to Mac and have installed R 2.1.1 and some packages, but now I'm
confused about the different users...

I installed R as admin, and also installed some extra packages as admin,
using the Package Installer and with the option "at system level (in R
framework)" enabled. I want to run R under my own user name, as a standard
user without admin privileges (we have set this rule to only use the admin
account for admin purposes to keep the computer as clean as possible). When
I want to do my analysis, which uses the siggenes package from Bioconductor,
I do the following: I open the package manager, check the checkmark for the
siggenes package to change its status to "loaded", and try to run my first
command (read.table). But then R gives me an error message, saying there are
no files in my User/Marije/Library/R/library folder. That's true, but as I
understood this folder is only for personal packages. Shouldn't I be able to
work with the packages I installed as an admin (which are located in the
Macintosh HD/Library/Frameworks/R.Framework/Versions/2.1.1/Resources/Library
folder)? As I said, I am new to Mac and find this setup of different users
the hardest part to fully understand (coming from Windows XP with only 1
user who has admin privileges).
