Windows guest eats as many CPU as available
Hello, I run Debian on my Laptop Lenovo X60s (with VT). I've created a Windows-XP as well as a Windows-Vista guest on it. Both, XP as well as Vista, eats as many CPU as available. Therefore the CPU always has high load and will never reduce cpu-frequenz or ventilator. Did this works as designed or should I modify something? Thanks in advance Matthias -- Don't Panic

how to plot a nice legend?
i'd like to plot a legend in my diagram. The diagram will be included in a TikZ LaTeX document later. I tried the legend() function, but - it can not find a good place it self where the legend fits and playing around with coordinates and scaling consumes a lot time - standard settings for the text need adjustment (linespacing is quite large and so on) Is there an alternative to

Why fails nls with "singular gradient" here? I post a minimal example on the bottom and would be very happy if someone could help me.

How to include files in .R?
Hi, may be its a very simple question, but i did not find any documentation about a 'include' command or something like this. I have to set many constants in my R-files and want to move all these to one file, so that i can reuse it in all other R-files. Something like include("~/R/myconstants.R") kind regards, -- Jonas Stein <news at jonasstein.de>

par.plot() for repeated measurements
Hello, I am using the package gamlss in R to plot repeated measurements. The command I am using is par.plot(). It works great except one thing about the label of the axises. I tried to label both x and y axises using ylab and xlab options. But the plot only gives variable variables. The labels did not show up. Below is the code I used. Any comments are appreciated!
