Dear DHines,
It looks to me as if there's some problem with your X11 installation. What
happens if you try to start X11 independently of R -- e.g., by entering
xterm in a (bash) terminal? I'm copying this response to Rob Goedman since
he's much more knowledgeable about these matters than I am.
I
Simon and Kasper,
I have gotten around the problem of the broken entry points by
directly installing source files by

Now, everything works like a charm (again).
As I am sure you know, there is still a
Dear all,
I am going to purchase a Power Mac (a new one, with Nehalem processor) for my
R-based microarray analyses. I use mainly Bioconductor packages, and a typical
dataset would consist of 50 microarrays with 40,000 datapoints each. To make
the right choice of processor and memory, I have
Hi Marije,
Personally, I would be more concerned with memory than processor.
Running out of memory can be an unpleasant surprise. Base R uses a
single core, but Simon Urbanek's multicore package (the most recent
version of which, 0.1-3, is dated today) does allow you to use multiple
cores at

I agree with Dan, memory will often be the limiting
factor. I added RAM (16GB total) to my ppc and have
had a much more productive environment, both for
32 bit and 64 bit applications.
Even if a single R session cannot benefit from multiple
cores, if you can break your processes into parallel

Dear Simon, Steven and Dan,
Thank you very much for your replies. I will look for an 'old' 8-core so I'll
have some memory left for a memory expansion (it's for work and there is only
$4000 CAD in the budget at the moment), or if I can't find an old one I'll get
a new 8-core with as much
